How to Reference Essays

Last Updated: January 8, 2024 Fact Checked

This article was co-authored by Alexander Peterman, MA . Alexander Peterman is a Private Tutor in Florida. He received his MA in Education from the University of Florida in 2017. There are 14 references cited in this article, which can be found at the bottom of the page.

When you begin writing a research essay, you must take into account the format of your writing and reference pages. There are several reference styles that may be assigned to you, including MLA (Modern Language Association), APA (American Psychological Association), and Chicago. Each one has its own set of rules. There's no need to familiarize yourself with all 3 unless you have to, but you do need to learn at least one if you’re in any field involving academic writing. Here are summaries of each style to help you start your essay on the right track.

Referencing Essays Templates

• You will need a citation directly after every sentence (or group of sentences if you're citing the same source in multiple consecutive sentences) containing information you didn't think of yourself. These include: paraphrases, facts, statistics, quotes, and examples.
• An in-text citation using MLA will simply have the author last name (or title if no author) followed by the page number. No comma between author and page number. For example: (Richards 456) Richards is the author last name, and 456 is the page number.
• If you have an author name (or title, if no author) but no page number, simply use author last name (or title).

• The easiest way to keep track of MLA citations while doing research is to copy and paste copyright information into a word processing document as you go, or to write it down in a notebook.
• Things to include for any source are author(s), date published, publisher, page number, volume and issue number, website, date accessed, anything that appears on the copyright page or indicates how to find it again. [2] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

• As an example, the format for a standard book citation using MLA style is as follows: Last name of author, First name. Title of Book. City published: Publisher Name, Year published. Source Medium.
• An MLA website citation looks like the following. If there's no author listed, begin citation with the name of the page: Last name, first name. "Page Title." Website Title. Publisher. Date published. Source Medium. Date accessed.
• An MLA scholarly article citation looks like the following: Last name, First name. "Title of Article." Title of Journal . Volume.Issue (Year): page numbers. Source Medium.
• Write the title of the main work (book, magazine, journal, website, etc.) in italics, or underline if you’re writing references by hand.
• Chapter or article titles should be in quotation marks.

• If there is no author listed, as is common on websites, simply skip the author’s name and begin the entry with the title of the work.
• Alphabetize by the first letter that appears in the entry, whether it has an author name or not.

• The formatting should be in Times New Roman font, size 12, with “Works Cited” centered at the top of a new page.
• Each entry should have hanging indent, meaning all lines below the first line are indented by half an inch.
• Make sure there is a period after each section of the citations. A period should always end the citation.

• Place a parenthetical citation at the end of every sentence (or group of sentences if you're using the same source for multiple consecutive sentences) containing information you didn't know before doing research.
• An in-text citation using APA will simply have the author last name (or title if no author) followed by the year it was published. No comma between name and year. For example: (Richards 2005) Richards is the author last name, and 2005 is the year.
• If you have an author name (or title if no author) but no page number, simply use author last name (or title). This is common when citing websites.
• APA document formatting is very important. APA papers are divided up into 4 sections: the title page, the abstract, the main body, and the references page. The citations of a research paper using APA appear in the References section, the last portion of an APA document. [7] X Research source

• To form APA reference page citations, you will need such information as author name(s), date published, website URL, date you accessed the website, title of work, and so on. [8] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

• For example, the format for an APA reference of a scholarly journal article is as follows: Author last name, First initial. (Year published). Article or chapter title. Journal or book title, Issue number , page number range. [10] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• The format for an APA book reference looks like: Last name, First name. (Year.) Title of Book: Capital letter also for subtitle . Location: Publisher.
• The format for an APA website reference looks like: Author, A.A. First name, & Author, B.B. (Date published.) Title of article. In Title of webpage or larger document or book (chapter or section number). Retrieved from URL address

• Capitalize the author's last name and first initial, followed by a period.
• Only capitalize the first word of a journal article title, unless the title contains a proper noun (called sentence case). Titles of books should preserve the published capitalization.
• Capitalize the city of publication, and use correct state abbreviations for states. Also capitalize the name of the publisher and end the reference with a period.
• The title of larger works, whether a book, journal, website, or magazine, is in italics (or underlined if handwriting), as is the issue number that appears right after the title. Titles for shorter works like articles and chapters should not have any indicative punctuation in an APA entry. [12] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• A period should end all citations.

Using Chicago Manual of Style

• For Notes and Bibliography, you will use a superscript at the instance of each quote in the text with a corresponding footnote at the end of the page. All footnotes are compiled into endnotes at the end of the work, on the bibliography page. [14] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• For Author Date, you will use parenthetical in-text citations that include author last name and year published, using no punctuation between name and year. The full version of each parenthetical citation is listed alphabetically on the references page. For example: (Simon 2011) Simon is the author last name, and 2011 is the year.
• You will need a citation directly after every sentence (or group of sentences if you're using the same source for multiple consecutive sentences) containing information you didn't think of yourself. These include: paraphrases, facts, statistics, quotes, and examples.

• If using a book, write down all pertinent information found on the copyright page, including the name of the publisher and the city and year of publication.
• For other sources, look for this information near the title of the piece you’re looking at. Publication date is often at the bottom of webpages.

• Title your references page “Bibliography” centered at the top of the page. Leave 2 blank lines between this title and the first entry, and one blank line between entries.
• Notes and Bibliography style uses footnotes for page endings and endnotes for chapter endings. The bibliography page will be an alphabetized list of all sources in hanging indent.
• An example format for a book is as follows: Last name, First name. Book Title . City: Publisher, Year.
• An example format for a chapter in a print scholarly journal is as follows: Author last name, first name. "Title of Chapter or Article." Book or journal Title Issue Number (Year): Page number range. (For an online scholarly journal article, tack on the following at the end: Date accessed. URL address.)
• When there is no known author, the entry should begin with the title of the document, whether it's a webpage, chapter, article, and so on.
• When there are multiple authors, the first listed author appears last name, first name, so that the citation is alphabetized by this author's last name. Subsequent authors are listed by first name, like this: Alcott, Louisa May, Charles Dickens, and Elizabeth Gaskell.
• Always end a citation with a period.

• When using Author Date style, title your references page “References” centered at the top of the page. Leave 2 blank lines between this title and the first entry, and 1 blank line between entries.
• Author Date style bibliographies should be organized alphabetically by last name (or by title if no author) in hanging indent.
• An example format for a book is as follows: Last name, first name. Year. Book Title . City Published: Publisher.
• An example format for a chapter in a print scholarly journal is as follows: Author last name, first name. Year. "Title of Chapter or Article." Book or journal title issue number: page numbers. (for an online scholarly journal article tack this onto the end: Date accessed. URL address.)
• An example format for a website is as follows: Name of Website. Year. "Page Title." Date last modified. Date accessed. URL address.

Expert Q&A

• You don't have to write each bibliography or reference entry on your own. You can download citation management software like Endnote [17] X Research source (purchase required on this one), Zotero [18] X Research source (it's free), or use websites like http://www.bibme.org/ and http://www.easybib.com/ . Select the name of your style manual before you begin creating citations. Copy and paste the citation into your bibliography or references list. Thanks Helpful 0 Not Helpful 0
• If you are assigned to write a paper or other written document in one of these styles, you need to purchase the style manual. It will contain nearly every instance not only of source citation, but paper formatting as well as grammar and punctuation that is unique to that style. Thanks Helpful 0 Not Helpful 0

APA Referencing (7th Ed.) Quick Guide | In-text Citations & References

Published on 18 January 2021 by Raimo Streefkerk . Revised on 22 May 2024.

This citation guide outlines the most important citation guidelines from the 7th edition APA Publication Manual (2020). Scribbr also offers free guides for the older APA 6th edition , MLA Style , and Chicago Style .

In-text citations are brief references in the running text that direct readers to the reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words.

An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170) .

Parenthetical vs. narrative citation

The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.

• Parenthetical citation: According to new research … (Smith, 2020) .
• Narrative citation: Smith (2020) notes that …

Multiple authors and corporate authors

The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.

Missing information

When the author, publication date or locator is unknown, take the steps outlined below.

Prevent plagiarism, run a free check.

APA references generally include information about the author , publication date , title , and source . Depending on the type of source, you may have to include extra information that helps your reader locate the source.

Reference examples

Citing a source starts with choosing the correct reference format. Use Scribbr’s Citation Example Generator to learn more about the format for the most common source types. Pay close attention to punctuation, capitalization, and italicization.

Generate APA citations for free

It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

On the first line of the page, write the section label “References” (in bold and centred). On the second line, start listing your references in alphabetical order .

Apply these formatting guidelines to the APA reference page:

• Double spacing (within and between references)
• Hanging indent of ½ inch
• Legible font (e.g. Times New Roman 12 or Arial 11)
• Page number in the top-right header

Which sources to include

On the reference page, you only include sources that you have cited in the text (with an in-text citation ). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).

How to Write an Academic Essay with References and Citations

#scribendiinc

Written by  Scribendi

If you're wondering how to write an academic essay with references, look no further. In this article, we'll discuss how to use in-text citations and references, including how to cite a website, how to cite a book, and how to cite a Tweet, according to various style guides.

You might need to cite sources when writing a paper that references other sources. For example, when writing an essay, you may use information from other works, such as books, articles, or websites. You must then inform readers where this information came from. Failure to do so, even accidentally, is plagiarism—passing off another person's work as your own.

You can avoid plagiarism and show readers where to find information by using citations and references. 

Citations tell readers where a piece of information came from. They take the form of footnotes, endnotes, or parenthetical elements, depending on your style guide. In-text citations are usually placed at the end of a sentence containing the relevant information. 

A reference list , bibliography, or works cited list at the end of a text provides additional details about these cited sources. This list includes enough publication information allowing readers to look up these sources themselves.

Referencing is important for more than simply avoiding plagiarism. Referring to a trustworthy source shows that the information is reliable. Referring to reliable information can also support your major points and back up your argument. 

Learning how to write an academic essay with references and how to use in-text citations will allow you to cite authors who have made similar arguments. This helps show that your argument is objective and not entirely based on personal biases.

How Do You Determine Which Style Guide to Use?

Often, a professor will assign a style guide. The purpose of a style guide is to provide writers with formatting instructions. If your professor has not assigned a style guide, they should still be able to recommend one. 

If you are entirely free to choose, pick one that aligns with your field (for example, APA is frequently used for scientific writing). 

Some of the most common style guides are as follows:

AP style for journalism

Chicago style for publishing

APA style for scholarly writing (commonly used in scientific fields)

MLA style for scholarly citations (commonly used in English literature fields)

Some journals have their own style guides, so if you plan to publish, check which guide your target journal uses. You can do this by locating your target journal's website and searching for author guidelines.

How Do You Pick Your Sources?

When learning how to write an academic essay with references, you must identify reliable sources that support your argument. 

As you read, think critically and evaluate sources for:

Objectivity

Keep detailed notes on the sources so that you can easily find them again, if needed.

Tip: Record these notes in the format of your style guide—your reference list will then be ready to go.

How to Use In-Text Citations in MLA

An in-text citation in MLA includes the author's last name and the relevant page number: 

(Author 123)

How to Cite a Website in MLA

Here's how to cite a website in MLA:

Author's last name, First name. "Title of page."

Website. Website Publisher, date. Web. Date

retrieved. <URL>

With information from a real website, this looks like:

Inc., n.d. Web. 22 Dec. 2021.

<https://www.scribendi.com/academy/articles/how_to_cite_a_website.en.html>

How Do You Cite a Tweet in MLA ?

MLA uses the full text of a short Tweet (under 140 characters) as its title. Longer Tweets can be shortened using ellipses. 

MLA Tweet references should be formatted as follows:

@twitterhandle (Author Name). "Text of Tweet." Twitter, Date Month, Year, time of

publication, URL.

With information from an actual Tweet, this looks like:

@neiltyson (Neil deGrasse Tyson). "You can't use reason to convince anyone out of an

argument that they didn't use reason to get into." Twitter, 29 Sept. 2020, 10:15 p.m.,

https://twitter.com/neiltyson/status/1311127369785192449 .

How to Cite a Book in MLA

Here's how to cite a book in MLA:

Author's last name, First name. Book Title. Publisher, Year.

With publication information from a real book, this looks like:

Montgomery, L.M. Rainbow Valley. Frederick A. Stokes Company, 1919.

How to Cite a Chapter in a Book in MLA

Publisher, Year, pp. page range.

Ezell, Margaret J.M. "The Social Author: Manuscript Culture, Writers, and Readers." The

Broadview Reader in Book History , edited by Michelle Levy and Tom Mole, Broadview

Press, 2015,pp. 375–394.

How to  Cite a Paraphrase in MLA

You can cite a paraphrase in MLA exactly the same way as you would cite a direct quotation. 

Make sure to include the author's name (either in the text or in the parenthetical citation) and the relevant page number.

How to Use In-Text Citations in APA

In APA, in-text citations include the author's last name and the year of publication; a page number is included only if a direct quotation is used: 

(Author, 2021, p. 123)

How to Cite a Website in APA

Here's how to cite a website in APA:

Author, A. A., & Author, B. B. (Year, Month. date of publication). Title of page. https://URL

Morris, N. (n.d.). How to cite a Tweet in APA, Chicago, and MLA.

Tip: Learn more about how to write an academic essay with  references to websites .

How Do You  Cite a Tweet in APA ?

APA refers to Tweets using their first 20 words. 

Tweet references should be formatted as follows:

Author, A. A. [@twitterhandle). (Year, Month. date of publication). First 20 words of the

Tweet. [Tweet] Twitter. URL

When we input information from a real Tweet, this looks like:

deGrasse Tyson, N. [@neiltyson]. (2020, Sept. 29). You can't use reason to convince anyone

out of an argument that they didn't use reason to get into. [Tweet] Twitter.

https://twitter.com/neiltyson/status/1311127369785192449

How to Cite a Book in APA

Here's how to cite a book in APA:   

Author, A. A. (Year). Book title. Publisher.

For a real book, this looks like:

Montgomery, L. M. (1919). Rainbow valley.

Frederick A. Stokes Company.

How to Cite a Chapter in a Book in APA

Author, A. A. (Year). Chapter title. In Editor Name (Ed.), Book Title (pp. page range).

With information from a real book, this looks like:

Ezell, M. J. M. (2014). The social author: Manuscript culture, writers, and readers. In

Michelle Levy and Tom Mole (Eds.), The Broadview Reader in Book History (pp. 375–

394). Broadview Press.

Knowing how to cite a book and how to cite a chapter in a book correctly will take you a long way in creating an effective reference list.

How to Cite a Paraphrase in APA

You can cite a paraphrase in APA the same way as you would cite a direct quotation, including the author's name and year of publication. 

In APA, you may also choose to pinpoint the page from which the information is taken.

Referencing is an essential part of academic integrity. Learning how to write an academic essay with references and how to use in-text citations shows readers that you did your research and helps them locate your sources.

Learning how to cite a website, how to cite a book, and how to cite a paraphrase can also help you avoid plagiarism —an academic offense with serious consequences for your education or professional reputation.

There are different versions of the Harvard referencing style. This guide is a quick introduction to the commonly-used Cite Them Right version. You will find further guidance available through the OU Library on the Cite Them Right Database .

For help and support with referencing and the full Cite Them Right guide, have a look at the Library’s page on referencing and plagiarism . If you need guidance referencing OU module material you can check out which sections of Cite Them Right are recommended when referencing physical and online module material .

This guide does not apply to OU Law undergraduate students . If you are studying a module beginning with W1xx, W2xx or W3xx, you should refer to the Quick guide to Cite Them Right referencing for Law modules .

Table of contents

In-text citations and full references.

• Secondary referencing
• Page numbers
• Citing multiple sources published in the same year by the same author

Full reference examples

Referencing consists of two elements:

• in-text citations, which are inserted in the body of your text and are included in the word count. An in-text citation gives the author(s) and publication date of a source you are referring to. If the publication date is not given, the phrase 'no date' is used instead of a date. If using direct quotations or you refer to a specific section in the source you also need the page number/s if available, or paragraph number for web pages.
• full references, which are given in alphabetical order in reference list at the end of your work and are not included in the word count. Full references give full bibliographical information for all the sources you have referred to in the body of your text.

To see a reference list and intext citations check out this example assignment on Cite Them Right .

Difference between reference list and bibliography

a reference list only includes sources you have referred to in the body of your text

a bibliography includes sources you have referred to in the body of your text AND sources that were part of your background reading that you did not use in your assignment

Back to top

Examples of in-text citations

You need to include an in-text citation wherever you quote or paraphrase from a source. An in-text citation consists of the last name of the author(s), the year of publication, and a page number if relevant. There are a number of ways of incorporating in-text citations into your work - some examples are provided below. Alternatively you can see examples of setting out in-text citations in Cite Them Right .

Note: When referencing a chapter of an edited book, your in-text citation should give the author(s) of the chapter.

Online module materials

(Includes written online module activities, audio-visual material such as online tutorials, recordings or videos).

When referencing material from module websites, the date of publication is the year you started studying the module.

Surname, Initial. (Year of publication/presentation) 'Title of item'. Module code: Module title . Available at: URL of VLE (Accessed: date).

OR, if there is no named author:

Are you feeling overwhelmed by referencing?

When you’re first asked to do referencing in an essay it can be hard to get your head around it. If it’s been a while since you were first taught how to reference, it can be intimidating to ask again how to do it!

I have so many students who consistently lose marks just because they didn’t get referencing right! They’re either embarrassed to ask for extra help or too lazy to learn how to solve the issues.

So, here’s a post that will help you solve the issues on your own.

Already think you’re good at referencing? No worries. This post goes through some surprising and advanced strategies for anyone to improve no matter what level you are at!

In this post I’m going to show you exactly how to reference in an essay. I’ll explain why we do it and I’ll show you 9 actionable tips on getting referencing right that I’m sure you will not have heard anywhere else!

The post is split into three parts:

• What is a Reference and What is a Citation?
• Why Reference? (4 Things you Should Know)
• How to Reference (9 Strategies of Top Students)

If you think you’ve already got a good understanding of the basics, you can jump to our 9 Advanced Strategies section.

Part 1: What is a Reference and What is a Citation?

What is a citation.

An in-text mention of your source. A citation is a short mention of the source you got the information from, usually in the middle or end of a sentence in the body of your paragraph. It is usually abbreviated so as not to distract the reader too much from your own writing. Here’s two examples of citations. The first is in APA format. The second is in MLA format:

• APA: Archaeological records trace the original human being to equatorial Africa about 250,000–350,000 years ago (Schlebusch & Jakobsson, 2018) .
• MLA: Archaeological records trace the original human being to equatorial Africa about 250,000–350,000 years ago (Schlebusch and Jakobsson 1) .

In APA format, you’ve got the authors and year of publication listed. In MLA format, you’ve got the authors and page number listed. If you keep reading, I’ll give some more tips on formatting further down in this article.

And a Reference is:

What is a Reference?

A reference is the full details of a source that you list at the end of the article. For every citation (see above) there needs to be a corresponding reference at the end of the essay showing more details about that source. The idea is that the reader can see the source in-text (i.e. they can look at the citation) and if they want more information they can jump to the end of the page and find out exactly how to go about finding the source.

Here’s how you would go about referencing the Schlebusch and Jakobsson source in a list at the end of the essay. Again, I will show you how to do it in APA and MLA formats:

• APA: Schlebusch, C. & Jakobsson, M. (2018). Tales of Human Migration, Admixture, and Selection in Africa. Annual Review of Genomics and Human Genetics , 11 (33), 1–24.
• MLA: Schlebusch, Carina and Mattias Jakobsson. “Tales of Human Migration, Admixture, and Selection in Africa.” Annual Review of Genomics and Human Genetics , vol. 11, no. 33, 2018, pp. 1–24.

In strategy 1 below I’ll show you the easiest and fool proof way to write these references perfectly every time.

One last quick note: sometimes we say ‘reference’ when we mean ‘citation’. That’s pretty normal. Just roll with the punches. It’s usually pretty easy to pick up on what our teacher means regardless of whether they use the word ‘reference’ or ‘citation’.

Part 2: Why Reference in an Essay? (4 Things you Should Know)

Referencing in an essay is important. By the time you start doing 200-level courses, you probably won’t pass the course unless you reference appropriately. So, the biggest answer to ‘why reference?’ is simple: Because you Have To!

Okay let’s be serious though … here’s the four top ‘real’ reasons to reference:

1. Referencing shows you Got an Expert’s Opinion

You can’t just write an essay on what you think you know. This is a huge mistake of beginning students. Instead this is what you need to do:

Top Tip: Essays at university are supposed to show off that you’ve learned new information by reading the opinions of experts.

Every time you place a citation in your paragraph, you’re showing that the information you’re presenting in that paragraph was provided to you by an expert. In other words, it means you consulted an expert’s opinion to build your knowledge.

If you have citations throughout the essay with links to a variety of different expert opinions, you’ll show your marker that you did actually genuinely look at what the experts said with an open mind and considered their ideas.

This will help you to grow your grades.

2. Referencing shows you read your Assigned Readings

Your teacher will most likely give you scholarly journal articles or book chapters to read for homework between classes. You might have even talked about those assigned readings in your seminars and tutorials.

Great! The assigned readings are very important to you.

You should definitely cite the assigned readings relevant to your essay topic in your evaluative essay (unless your teacher tells you not to). Why? I’ll explain below.

• Firstly, the assigned readings were selected by your teacher because your teacher (you know, the person who’s going to mark your essay) believes they’re the best quality articles on the topic. Translation: your teacher gave you the best source you’re going to find. Make sure you use it!
• Secondly, by citing the assigned readings you are showing your teacher that you have been paying attention throughout the course. You are showing your teacher that you have done your homework, read those assigned readings and paid attention to them. When my students submit an essay that has references to websites, blogs, wikis and magazines I get very frustrated. Why would you cite low quality non-expert sources like websites when I gave you the expert’s article!? Really, it frustrates me so, so much.

So, cite the assigned readings to show your teacher you read the scholarly articles your teacher gave to you. It’ll help you grow your marks.

3. Referencing deepens your Knowledge

Okay, so you understand that you need to use referencing to show you got experts’ opinions on the topic.

But there’s more to it than that. There’s actually a real benefit for your learning.

If you force yourself to cite two expert sources per paragraph, you’re actually forcing yourself to get two separate pieces of expert knowledge. This will deepen your knowledge!

So, don’t treat referencing like a vanity exercise to help you gain more marks. Actually view it as an opportunity to develop deeper understandings of the topic!

When you read expert sources, aim to pick up on some new gems of knowledge that you can discuss in your essays. Some things you should look out for when finding sources to reference:

• Examples that link ideas to real life. Do the experts provide real-life examples that you can mention in your essay?
• Facts and figures. Usually experts have conducted research on a topic and provide you with facts and figures from their research. Use those facts and figures to deepen your essay!
• Short Quotes. Did your source say something in a really interesting, concise or surprising way? Great! You can quote that source in your essay .
• New Perspectives. Your source might give you another perspective, angle or piece of information that you can add to your paragraph so that it’s a deep, detailed and interesting paragraph.

So, the reason we ask you to reference is at the end of the day because it’s good for you: it helps you learn!

4. Referencing backs up your Claims

You might think you already know a ton of information about the topic and be ready to share your mountains of knowledge with your teacher. Great!

So, should you still reference?

Yes. Definitely.

You need to show that you’re not the only person with your opinion. You need to ‘stand on the shoulders of giants.’ Show what other sources have said about your points to prove that experts agree with you.

You should be saying: this is my opinion and it’s based on facts, expert opinions and deep, close scrutiny of all the arguments that exist out there .

If you make a claim that no one else has made, your teacher is going to be like “Have you even been reading the evidence on this topic?” The answer, if there are no citations is likely: No. You haven’t.

Even if you totally disagree with the experts, you still need to say what their opinions are! You’ll need to say: “This is the experts’ opinions. And this is why I disagree.”

So, yes, you need to reference to back up every claim. Try to reference twice in every paragraph to achieve this.

Part 3: Strategies for How to Reference in an Essay (9 Strategies of Top Students)

Let’s get going with our top strategies for how to reference in an essay! These are strategies that you probably haven’t heard elsewhere. They work for everyone – from beginner to advanced! Let’s get started:

1. Print out your Reference Style Cheat Sheet

Referencing is hard and very specific. You need to know where to place your italics, where the commas go and whether to use an initial for full name for an author.

There are so many details to get right.

And here’s the bad news: The automated referencing apps and websites nearly always get it wrong! They tell you they can generate the citation for you. The fact of the matter is: they can’t!

Here’s the best way to get referencing right: Download a referencing cheat sheet and have it by your side while writing your essay.

Your assignment outline should tell you what type of referencing you should use. Different styles include: APA Style, MLA Style, Chicago Style, Harvard Style, Vancouver Style … and many more!

You need to find out which style you need to use and download your cheat sheet. You can jump onto google to find a cheat sheet by typing in the google bar:

Download a pdf version of the referencing style cheat sheet, print it out, and place it on your pinboard or by your side when writing your essay.

2. Only cite Experts

There are good and bad sources to cite in an essay.

You should only cite sources written, critiqued and edited by experts. This shows that you have got the skill of finding information that is authoritative. You haven’t just used information that any old person popped up on their blog. You haven’t just gotten information from your local newspaper. Instead, you got information from the person who is an absolute expert on the topic.

Here’s an infographic listing sources that you should and shouldn’t cite. Feel free to share this infographic on social media, with your teachers and your friends:

3. Always use Google Scholar

Always. Use. Google. Scholar.

Ten years ago students only had their online university search database to find articles. Those university databases suck. They rarely find the best quality sources and there’s always a big mix of completely irrelevant sources mixed in there.

Google Scholar is better at finding the sources you want. That’s because it looks through the whole article abstract and analyses it to see if it’s relevant to your search keywords. By contrast, most university search databases rely only on the titles of articles.

Use the power of the best quality search engine in the world to find scholarly sources .

Note: Google and Google Scholar are different search engines.

To use Google Scholar, go to: https://scholar.google.com

Then, search on google scholar using keywords. I’m going to search keywords for an essay on the topic: “What are the traits of a good nurse?”

If you really like the idea of that first source, I recommend copying the title and trying your University online search database. Your university may give you free access.

4. Cite at least 50% sources you found on your Own Research

Okay, so I’ve told you that you should cite both assigned readings and readings you find from Google Scholar.

Here’s the ideal mix of assigned sources and sources that you found yourself: 50/50.

Your teacher will want to see that you can use both assigned readings and do your own additional research to write a top essay . This shows you’ve got great research skills but also pay attention to what is provided in class.

I recommend that you start with the assigned readings and try to get as much information out of them, then find your own additional sources beyond that using Google Scholar.

So, if your essay has 10 citations, a good mix is 5 assigned readings and 5 readings you found by yourself.

5. Cite Newer Sources

As a general rule, the newer the source the better .

The best rule of thumb that most teachers follow is that you should aim to mostly cite sources from the past 10 years . I usually accept sources from the past 15 years when marking essays.

However, sometimes you have a really great source that’s 20, 30 or 40 years old. You should only cite these sources if they’re what we call ‘seminal texts’. A seminal text is one that was written by an absolute giant in your field and revolutionized the subject.

Here’s some examples of seminal authors whose old articles you would be able to cite despite the fact that they’re old:

• Education: Vygotsky, Friere, Piaget
• Sociology: Weber, Marx, C. Wright Mills
• Psychology: Freud, Rogers, Jung

Even if I cite seminal authors, I always aim for at least 80% of my sources to have been written in the past 10 years.

6. Reference twice per Paragraph

How much should you reference?

Here’s a good strategy: Provide two citations in every paragraph in the body of the essay.

It’s not compulsory to reference in the introduction and conclusion . However, in all the other paragraphs, aim for two citations.

Let’s go over the key strategies for achieving this:

• These two citations should be to different sources, not the same sources twice;
• Two citations per paragraph shows your points are backed up by not one, but two expert sources;
• Place one citation in the first half of the paragraph and one in the second half. This will indicate to your marker that all the points in the whole paragraph are backed up by your citations.

This is a good rule of thumb for you when you’re not sure when and how often to reference. When you get more confident with your referencing, you can mix this up a little.

7. The sum total of your sources should be minimum 1 per 150 words

You can, of course, cite one source more than once throughout the essay. You might cite the same source in the second, fourth and fifth paragraphs. That’s okay.

But, you don’t want your whole essay to be based on a narrow range of sources. You want your marker to see that you have consulted multiple sources to get a wide range of information on the topic. Your marker wants to know that you’ve seen a range of different opinions when coming to your conclusions.

When you get to the end of your essay, check to see how many sources are listed in the end-text reference list. A good rule of thumb is 1 source listed in the reference list per 150 words. Here’s how that breaks down by essay size:

• 1500 word essay: 10 sources (or more) listed in the reference list
• 2000 word essay: 13 sources (or more) listed in the reference list
• 3000 word essay: 20 sources (or more) listed in the reference list
• 5000 word essay: 33 sources (or more) listed in the reference list

8. Instantly improve your Reference List with these Three Tips

Here’s two things you can do to instantly improve your reference list. It takes less than 20 seconds and gives your reference list a strong professional finish:

a) Ensure the font size and style are the same

You will usually find that your whole reference list ends up being in different font sizes and styles. This is because you tend to copy and paste the titles and names in the citations from other sources. If you submit the reference list with font sizes and styles that are not the same as the rest of the essay, the piece looks really unprofessional.

So, quickly highlight the whole reference list and change its font to the same font size and style as the rest of your essay. The screencast at the end of Step 8 walks you through this if you need a hand!

b) List your sources in alphabetical order.

Nearly every referencing style insists that references be listed in alphabetical order. It’s a simple thing to do before submitting and makes the piece look far more professional.

If you’re using Microsoft Word, simply highlight your whole reference list and click the A>Z button in the toolbar. If you can’t see it, you need to be under the ‘home’ tab (circled below):

You’ve probably never heard of a hanging indent. It’s a style where the second line of the reference list is indented further from the left-hand side of the page than the first line. It’s a strategy that’s usually used in reference lists provided in professional publications.

If you use the hanging indent, your reference list will look far more professional.

Here’s a quick video of me doing it for you:

9. Do one special edit especially for Referencing Style

The top students edit their essays three to five times spaced out over a week or more before submitting. One of those edits should be specifically for ensuring your reference list adheres to the referencing style that your teacher requires.

To do this, I recommend you get that cheat sheet printout that I mentioned in Step 1 and have it by your side while you read through the piece. Pay special attention to the use of commas, capital letters, brackets and page numbers for all citations. Also pay attention to the reference list: correct formatting of the reference list can be the difference between getting the top mark in the class and the fifth mark in the class. At the higher end of the marking range, things get competitive and formatting of the reference list counts.

A Quick Summary of the 9 Top Strategies…

Follow the rules of your referencing style guide (and that cheat sheet I recommended!) and use the top 9 tips above to improve your referencing and get top marks. Not only will your referencing look more professional, you’ll probably increase the quality of the content of your piece as well when you follow these tips!

Here’s a final summary of the 9 top tips:

APA In-Text Citations and Sample Essay 7th Edition

This handout focuses on how to format in-text citations in APA.

Proper citation of sources is a two-part process . You must first cite each source in the body of your essay; these citations within the essay are called in-text citations . You MUST cite all quoted, paraphrased, or summarized words, ideas, and facts from sources. Without in-text citations, you are technically in danger of plagiarism, even if you have listed your sources at the end of the essay.

In-text citations point the reader to the sources’ information on the references page. The in-text citation typically includes the author's last name and the year of publication. If you use a direct quote, the page number is also provided.

More information can be found on p. 253 of the 7th edition of the Publication Manual of the American Psychological Association.

Citation Rules

Direct quotation with the author named in the text.

Heinze and Lu (2017) stated, “The NFL shifted its responses to institutional change around concussions significantly as the field itself evolved” (p. 509).

Note: The year of publication is listed in parenthesis after the names of the authors, and the page number is listed in parenthesis at the end of the quote.

Direct Quotation without the Author Named in the Text

As the NFL developed as an organization, it “shifted its responses to institutional change around concussions significantly” (Heinze & Lu, 2017, p. 509).

Note: At the end of the quote, the names of the authors, year of publication, and page number are listed in parenthesis.

Paraphrase with 1-2 Authors

As the NFL developed as an organization, its reactions toward concussions also transformed (Heinze & Lu, 2017).

Note: For paraphrases, page numbers are encouraged but not required.

Paraphrase with 3 or More Authors

To work toward solving the issue of violence in prisons begins with determining aspects that might connect with prisoners' violent conduct (Thomson et al., 2019).

Direct Quotation without an Author

The findings were astonishing "in a recent study of parent and adult child relationships" ("Parents and Their Children," 2007, p. 2).

Note: Since the author of the text is not stated, a shortened version of the title is used instead.

Secondary Sources

When using secondary sources, use the phrase "as cited in" and cite the secondary source on the References page.

In 1936, Keynes said, “governments should run deficits when the economy is slow to avoid unemployment” (as cited in Richardson, 2008, p. 257).

Long (Block) Quotations

When using direct quotations of 40 or more words, indent five spaces from the left margin without using quotation marks. The final period should come before the parenthetical citation.

At Meramec, an English department policy states:

To honor and protect their own work and that of others, all students must give credit to proprietary sources that are used for course work. It is assumed that any information that is not documented is either common knowledge in that field or the original work of that student. (St. Louis Community College, 2001, p. 1)

Website Citations

If citing a specific web document without a page number, include the name of the author, date, title of the section, and paragraph number in parentheses:

In America, “Two out of five deaths among U.S. teens are the result of a motor vehicle crash” (National Center for Injury Prevention and Control, 2004, Overview section, para. 1).

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

Article (with doi).

Alvarez, E., & Tippins, S. (2019). Socialization agents that Puerto Rican college students use to make financial decisions. Journal of Social Change , 11 (1), 75–85. https://doi.org/10.5590/JOSC.2019.11.1.07

Laplante, J. P., & Nolin, C. (2014). Consultas and socially responsible investing in Guatemala: A case study examining Maya perspectives on the Indigenous right to free, prior, and informed consent. Society & Natural Resources , 27 , 231–248. https://doi.org/10.1080/08941920.2013.861554

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list. Also see our Quick Answer FAQ, "Can I use the DOI format provided by library databases?"

Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House.” PLoS ONE , 13 (3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972

For journal articles that are assigned article numbers rather than page ranges, include the article number in place of the page range.

For more on citing electronic resources, see  Electronic Sources References .

Article (Without DOI)

Found in a common academic research database or in print.

Casler , T. (2020). Improving the graduate nursing experience through support on a social media platform. MEDSURG Nursing , 29 (2), 83–87.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

Found on an Open Access Website

Eaton, T. V., & Akers, M. D. (2007). Whistleblowing and good governance. CPA Journal , 77 (6), 66–71. http://archives.cpajournal.com/2007/607/essentials/p58.htm

Provide the direct web address/URL to a journal article found on the open web, often on an open access journal's website. In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Weinstein, J. A. (2010).  Social change  (3rd ed.). Rowman & Littlefield.

If the book has an edition number, include it in parentheses after the title of the book. If the book does not list any edition information, do not include an edition number. The edition number is not italicized.

American Nurses Association. (2015). Nursing: Scope and standards of practice (3rd ed.).

If the author and publisher are the same, only include the author in its regular place and omit the publisher.

Lencioni, P. (2012). The advantage: Why organizational health trumps everything else in business . Jossey-Bass. https://amzn.to/343XPSJ

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

Chapter in an Edited Book

Poe, M. (2017). Reframing race in teaching writing across the curriculum. In F. Condon & V. A. Young (Eds.), Performing antiracist pedagogy in rhetoric, writing, and communication (pp. 87–105). University Press of Colorado.

Include the page numbers of the chapter in parentheses after the book title.

Christensen, L. (2001). For my people: Celebrating community through poetry. In B. Bigelow, B. Harvey, S. Karp, & L. Miller (Eds.), Rethinking our classrooms: Teaching for equity and justice (Vol. 2, pp. 16–17). Rethinking Schools.

Also include the volume number or edition number in the parenthetical information after the book title when relevant.

Freud, S. (1961). The ego and the id. In J. Strachey (Ed.),  The standard edition of the complete psychological works of Sigmund Freud  (Vol. 19, pp. 3-66). Hogarth Press. (Original work published 1923)

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com  

A few notes on citing course materials:

• [Lecture notes]
• [Course handout]
• [Study notes]
• It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
• If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note:  The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Citing Tempo Classroom Resources

Clear author: 

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Brightspace. https://mytempo.waldenu.edu

Dictionary Entry

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Online Video/Webcast

Walden University. (2013).  An overview of learning  [Video]. Walden University Canvas.  https://waldenu.instructure.com  

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

For videos from streaming sites, use the person or organization who uploaded the video in the author space to ensure retrievability, whether or not that person is the speaker in the video. A username can be provided in square brackets. As a change from APA 6 to APA 7, include the publisher after the title, and do not use "Retrieved from" before the URL. See APA 7, Section 10.12 for more information and examples.

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Citing and referencing information can be daunting for students who do not understand the principles.

There are numerous ways to reference. Different institutions, departments or lecturers may require different styles so check with your teacher, lecturer or instructor if you are unsure.

Bad referencing is a common way for students to lose marks in assignments so it is worth taking the time and effort to learn how to reference correctly.

Why Do We Cite and Reference?

When writing any academic essay, paper, report or assignment, you need to highlight your use of other author's ideas and words so that you:

• Give the original author credit for their own ideas and work
• Validate your arguments
• Enable the reader to follow up on the original work if they wish to
• Enable the reader to see how dated the information might be
• Prove to your tutors/lecturers that you have read around the subject
• Avoid plagiarism

Referencing Styles

There are many different styles of referencing, including Harvard, APA (from the American Psychological Association), Chicago and Vancouver. The Harvard referencing system is of the most popular styles and the remainder of this article deals with this system. However, your university may prefer the use of a different system so check with your lecturer or in your course information as to which referencing style to use.

What is Plagiarism?

• Presenting another's ideas as if they are your own – either directly or indirectly
• Copying or pasting text and images without saying where they came from
• Not showing when a quote is a quote
• Summarising information without showing the original source
• Changing a few words in a section of text without acknowledging the original author

Plagiarism is a serious academic offence.  You are likely to be awarded 0% for an assignment which has evidence of plagiarism. If you continue to plagiarise then you may be excluded from your course.

Most universities will want a signed declaration with submitted work to say that you have not plagiarised. 

Universities use anti-plagiarism software to quickly find plagiarised work. This software usually draws on huge databases of web sources, books, journals and all previously submitted student work to compare your work to so you will be found out.

Therefore, if you plagiarise, you are likely to be caught so don't take the risk and reference properly.

Be Organised

When writing an essay, report, dissertation or other piece of academic work, the key to referencing is organisation. As you go along, keep notes of the books and journal articles you have read and the websites you have visited as part of your research process.

There are various tools to help here. Your university may be able to provide you with some specialist software (Endnote – www.endnote.com ) or you can simply keep a list in a document or try Zotero ( www.zotero.org ) a free plugin for the Firefox browser.

What Needs to be Recorded?

Record as much information as possible in references to make finding the original work simple.

Include the author/s name/s where possible. You should write the surname (last name) first followed by any initials.  If there are more than three authors then you can cite the first author and use the abbreviation 'et al', meaning 'and all'.

For one, two or three authors: Jones A, Davies B, Jenkins C

For more than three authors Jones A et al.

For some sources, especially websites, the name of the author may not be known. In such cases either use the organisation name or the title of the document or webpage.

Example:  SkillsYouNeed or What Are Interpersonal Skills.

Date of Publication

You should include the year of publication or a more specific date if appropriate, for journal or newspaper articles/stories. For webpages look for the when the page was last updated. Include dates in brackets (2020) after author information. If no date can be established, then put (no date).

Title of Piece

Include the title of the piece; this could be the name of the book, the title of a journal article or webpage. Titles are usually written in italics . For books you should also include the edition (if not the first) to make finding information easier. Often when books are republished information remains broadly the same but may be reordered, therefore page numbers may change between editions.

Publisher Information

Usually only relevant for books, but for these you should include the publisher name and place of publication.

Page Numbers

If you are referencing a particular part of a book, then you should include the page number/s you have used in your work. Use p. 123 to indicate page 123 or pp. 123-125 to indicate multiple pages.

URL and Date Accessed

For webpages you need to include the full URL of the page (http://www... etc.) and the date you last accessed the page. The web is not static and webpages can be changed/updated/removed at any time, so it is therefore important to record when you found the information you are referencing.

Once you have recorded the information, you have everything you need in order to reference correctly. Your work should be both referenced in the text and include a reference list or bibliography at the end. The in text reference is an abbreviated version of the full reference in your reference list.

Direct Quotes

If you are directly quoting in your text you should enclose the quote in quotation marks, and include author information:

"Communication is simply the act of transferring information from one place to another." SkillsYouNeed (2019)

For longer direct quotations it may be neater to indent the quotation in its own paragraph.

Your reference list should then include the full version of the reference:

SkillsYouNeed (2022) What is Communication? [online] available at www.skillsyouneed.com/ips/what-is-communication.html (Accessed October 14 2022)

For a book you would use, in your text:

“Long before the twelfth century rhetoricians had collected quotations, particularly from classical authors, into anthologies called florilegia…” (Clanchy, M.T, 1993)

The reference list would then include the full reference:

Clanchy, M.T. (1993) From Memory to Written Record England 1066 – 1307 Oxford, Blackwell, p. 115

The same rules also apply when you are referencing indirectly and you have not included a direct quote. If you have used the ideas of another source, reference both in your text at the relevant point and in your reference list or bibliography at the end of your document.

Our eBooks are ideal for students at all stages of education, school, college and university. They are full of easy-to-follow practical information that will help you to learn more effectively and get better grades.

Additional Information

When quoting you may sometimes want to leave out some words , in which case use … (three dots).

"Communication is … transferring information from one place to another"

If you need to add words to a quote for clarity, then square brackets are used:

“Communication is simply the act [in communication skills] of transferring information from one place to another.”

You can use [sic] to note an original error and/or foreign spelling , SkillsYouNeed is a UK site and therefore uses UK spellings:

"The color [sic] of the water..."

Reference Your Essay

Referencing is a system that allows you to acknowledge the contributions and work of others in your writing by citing your sources. A feature of academic writing is that it contains references to the words, information and ideas of others.

All academic essays MUST contain references. Referencing guards against plagiarism , a serious academic offence. Plagiarism is copying someone else's words or ideas and presenting them as your own.

Make sure you are familiar with the referencing style your faculty or school requires. Most have guides specifying the system they prefer. Often Schools/Faculties don't mind which system you use as long as it is consistent . If this is the case, use the system you are most comfortable with.

Reference lists

Remember to list all the books and articles you use for the essay in a Reference List. This is a list of all works cited in your essay and should be the final page.

Rules for referencing and citation

Why  reference essays.

Referencing your work properly is one of the most important ways that you can establish the authority of your ideas, and allows you to situate your own ideas and arguments in relation to those of other scholars.

Referencing is also an important way of acknowledging your debts to other scholars. Properly referencing your work is one of the best ways of avoiding plagiarism.

You can find out more about referencing by browsing the university's  academic integrity pages

How to reference essays

The English department requires that you reference your essays in accordance with either the Chicago Manual of Style or the MLA Style guide.

The university produces handy guides to these referencing systems, which you should consult:

• Chicago style referencing
• MLA style referencing

How to Write an Essay in MLA Format | For Students

Starting from when I entered high school, the importance of submitting assignments in a particular format became a top priority. I quickly realized the significance of adhering to these guidelines, as they remained essential throughout my academic journey. You never know when the need for proper formatting will arise. At first, it may seem overwhelming, but in this simple guide, I'll show you how to write an essay in MLA format [For Students].

When is MLA format used?

MLA format is created by the Modern Language Association which is a standardized way to format academic papers and cite sources. It’s mainly used for subjects in the humanities, like literature, philosophy, and the arts. Unlike APA or Chicago formats, which are used for social sciences and history, MLA puts a strong emphasis on the authorship of sources.

Most students will need to use MLA format at some point, especially in humanities courses. It’s essential for essays, research papers, and other assignments in these subjects.

General Guidelines/ Rules of MLA Formatting

The first step to learning how to write an essay in MLA format for students is to get familiar with the general guidelines. It's all about following the rules to get your paper formatted in the MLA style:

Margins and Font:

Set 1-inch margins on all sides.

Choose a readable font such as Times New Roman, 12-point size.

Double-space the entire document, including block quotes (quotes longer than four lines), notes, and the works cited page.

Paragraph Indentation:

Indent the first line of each paragraph by 0.5 inches (press Tab key once).

Punctuation:

Utilize standard punctuation marks and maintain consistency with punctuation, italics, and quotation marks throughout your paper.

Quotations:

Use double quotation marks (" ") for direct quotes.

For quotes longer than four lines, format as a block quote: start on a new line, indent 0.5 inches from the left margin (without quotation marks), and keep double-spacing.

Here is an essay MLA format template for your reference:

How to Set up MLA Format Essay [Step-by-Step]

So we have seen the general guidelines in the above example and also saw an essay MLA format example/sample showing what our final MLA format will look like. However, going through guidelines is not enough when you're learning how to write an essay in MLA format in Word or PDF format. You need a professional writing software that not only provides the tools but also allows you to use them easily.

Therefore, I will be using WPS Writer as my partner in writing an essay in MLA format, and I would recommend students to download WPS Writer from their website so that you can easily follow this guide. And yes, it is completely free. So let's begin formatting an essay to MLA format in WPS Writer:

1. Page Margins

So the first step is to ensure that our page margins are set to 1 inch on every side. Setting the margins first would help you avoid any formatting errors if you do this at a later stage. To set page margins in WPS Writer:

Step 1: Open WPS Writer and visit the “Page Layout” tab in the toolbar.

Step 2: Find the Page Margin options on the far left of the Page Layout ribbon.

Step 3: Set all the margin fields—top, bottom, left, and right—to 1 inch.

2. Line Spacing

Next, we need to ensure that the line spacing is set to double spacing . This helps improve readability and ensures your paper meets MLA formatting standards. To set double line spacing in WPS Writer:

Step 1: In WPS Writer, go to the “Home” tab in the toolbar.

Step 2: Find and click the “Line Spacing” option in the Home ribbon.

Step 3: In the Line Spacing drop-down, click on More.

Step 4: The Paragraph window will pop up. Visit the Spacing section and in the Line Spacing field, select “Double”.

Step 5: After that, click on OK to exit the Paragraph window.

Note: We can also use the keyboard shortcut CTRL + 2 to quickly change the line spacing to double.

3. Header- In the Upper-Left Corner

After setting the page settings, let's move on to the content of the essay, starting with the header in the following order:

Student's Name

Professor's Name

Course and Course Code

Due Date in the format DD Month, Year

Step 1: Follow the order to enter the header into your essay.

Step 2: To make the Header left aligned, visit the Home tab and then click on the “Align Text Left” icon.

Step 3: After entering the header, make sure the Font is set to "Times New Roman" in the Fonts field in the Home ribbon.

Step 4: After the font, the font size should also be set to "12." Therefore, make the change in the "Font Size" field in the Home ribbon.

4. Last Name & Page Numbers- In the Upper-Right Corner

MLA Format requires a running header that includes your last name along with the page number on the top right corner of every page. Let's see how we can create our running header for the MLA Format:

Step 1: Double-click on the Header area to open the Header/Footer in WPS Writer.

Step 2: Now type your last name and set its alignment to right by clicking on the “Align Text Right” icon in the Home ribbon.

Step 3: To add the page number, click on the "Page Number" option in the Header/Footer ribbon and select the "Header right" option to insert a page number in the right corner.

Once the running header has been added, it is important to set the font size of the running header to 12 and the font to "Times New Roman".

Step 4: Simply select your running header and click on the Home tab.

Step 5: In the Home tab, change the Font to "Times New Roman" in the Fonts field.

Step 6: To change the font size, in the Home ribbon, enter "12" in the Font size field.

The last setting for the running header is to set the header margin to "0.5 inches":

Step 7: Head over to the Header/Footer tab.

Step 8: In the Header/Footer ribbon, enter "0.5 in" in the “Header Height” field to set the header margin to 0.5 inches.

5. Title of Essay- On the Line Below the Date

After the header and running header, let's begin our essay with the title of our essay. Remember the rules:

The title should be center aligned.

The title should not be bolded, italicized, or placed in quotation marks unless it includes the title of a source (e.g., a book or movie title).

Step 1: Insert the title right below the header and visit the Home tab.

Step 2: In the Home ribbon, click on the “Center” icon to center align the title.

6. Headings and Subheadings- Into Sections

Headings and subheadings are important as they give reference to the reader. There are no hard and fast rules for their formatting, except that they need to be center aligned. You can set the font style to bold to help the reader distinguish them.

Step 1: Enter your heading below the title of the essay and visit the Home tab.

Step 2: In the Home ribbon, click on “Center” to align the heading to the center.

Step 3: To change the font style to bold, in the Home ribbon, click on the “Bold” icon right below the font field.

7. In-text Citation

In MLA format, in-text citations use parenthetical references to indicate quotes or ideas from another author. Here's a step-by-step guide on how to do in-text citations:

Step 1: When you quote or paraphrase from a source, use the author's last name and the page number where the information is found.

Step 2:  After the quote or paraphrase, place the citation in parentheses. The citation should include the author's last name followed by the page number without a comma between them.

Step 3: The parenthetical citation should be placed before the period at the end of the sentence.

8. Works Cited Page

Finally, you will need to cite all the sources you took assistance from in writing your paper. Follow the following steps to understand how to cite your work in MLA format.

Step 1: Use a page break to start a fresh new page with the title "Works Cited." The heading "Works Cited" will follow similar heading guidelines as before.

Step 2: Double-space all entries and do not add extra spaces between entries.

Step 3: Use a hanging indent for each entry. The first line of each citation is flush with the left margin, and subsequent lines are indented by 0.5 inches simply using the “Tab” key..

Step 4: List entries in alphabetical order by the author's last name. If a work has no author, alphabetize it by the first significant word in the title.

Step 5: Format your sources as mentioned below for respective source medium:

Books Format: Author's Last Name, First Name. Title of Book. Publisher, Year of Publication.

Articles in Journals Format: Author's Last Name, First Name. "Title of Article." Title of Journal, vol. number, no. number, Year, pages.

Websites Format: Author's Last Name, First Name (if available). "Title of Webpage." Title of Website, Publisher, Date of Publication, URL.

Bonus Tips: How to Convert Word to PDF without losing Format

Once you finish writing your essay, the next challenge is converting it from Microsoft Word to PDF without losing formatting. This can be frustrating because sometimes the formatting doesn't stay the same.

To avoid this issue, use WPS Office . It offers strong PDF features and keeps APA and MLA formatting intact. On the other hand, Microsoft Word 365, though widely used, may occasionally struggle to keep formatting consistent when converting to PDF. It's important to choose tools that prioritize preserving the look and structure of your academic work.

Here is how you can use WPS PDF to convert your essay documents to PDF without compromising on the quality:

Step 1: On WPS Writer, click on the Menu button on the top left corner of the screen.

Step 2: Now simply click on the “Export to PDF” option in the Menu.

Step 3: The Export to PDF window will open. Here, you can alter a few settings such as the output path. After going through the settings, simply click on Export to PDF to save the essay document as a PDF.

FAQs about writing an essay in MLA format

1. how to cite an image in mla.

To cite an image in MLA style, you need to format the citation based on where the image was viewed. For online images, the citation should follow this structure:

MLA format:

Creator’s last name, First name. “Image Title” or Description of the image. Website Name in italics, Day Month Year, URL.

MLA Works Cited entry:

Smith, Jamie. “Vintage Cars.” Travel With Us, 15 Mar. 2023, www.travelwithus.com/vintage-cars.

MLA in-text citation:

(Smith) Note: If you discover an image through a search engine such as Google, ensure that you credit and link to the website that hosts the image, rather than the search engine.

2. Do I need to include a title page in my MLA essay?

In most instances, an MLA-formatted essay does not necessitate a separate title page unless instructed otherwise by your instructor. Instead, begin your essay with a header and center the title on the subsequent line.

3. How to Cite a Website in MLA?

To cite a website in MLA style, you should include the author’s name (if known), the title of the page in quotation marks, the name of the website in italics, the publication date, and the URL without "https://". If the identity of the author is not known, start with the title of the page. If the publication date is unavailable or if there's a possibility of content modifications, include an access date at the end.

Author’s last name, First name. “Title of Page.” Website Name, Day Month Year, URL.

Recommendations

Recommendations and references have a similar role in a selective process. Recommendations are usually formal, confidential letters provided to a graduate school or other academic-based program, while references are used by employers to confirm qualifications before making an offer.

Letters of Recommendation

Letters of recommendation provide a detailed and persuasive argument for why and how the subject of the letter (you) should be admitted to the program you are applying for.

Typically, letters of recommendation are used as part of an application, most often for advanced degree programs but also for selective programs like fellowships, scholarships, or experiential learning. For example, a letter of recommendation is required for applications to the Yawkey Nonprofit Internship Program.

These letters are usually sent directly to the admissions office or selection committee rather than provided to the applicant. Some recommenders also choose to provide a copy to the person they are writing the letter about.

Ask people who can write about your relevant strengths and who will submit a recommendation on time.

You may need to ask different people, depending on what you are applying for. Some applications may require a personal recommender as well as an academic or professional one.

• Ask those who know you well: They will be able to write a more comprehensive and detailed letter.
• Ask those who can write a strong and relevant recommendation: You want a recommender who thinks highly of you—particularly in areas relevant to what you are applying for.
• Ask those who can submit the letter on time: A glowing letter that arrives late won’t help you.

In order to plan ahead, have an honest conversation with the people you would like to ask for a recommendation well in advance of starting your application.

• Could they be a strong recommender?
• If not, what steps can you take to improve or to help them get to know you better?
• What are the qualities or criteria that they use to determine whether they can provide a strong recommendation?

When to Ask

Ask at least three weeks in advance of the submission date.

Give them plenty of time to make a decision about writing the letter and so that it is as persuasive as possible. Make sure they are aware of the official deadline in addition to your timeline, especially if you would like them to submit the letter early.

Ask in an email.

Wait for an Honest Answer

The person needs time to consider your request. You want all recommendations to be strong ones. If someone you ask feels as though they cannot write a strong recommendation, it is better that they decline, so that you can ask someone else.

Package the Details

You should include all of the necessary details as well as additional helpful information all in one place. This makes it easier for them to reference what they need to know and make a decision. If the topic initially comes up during a meeting or conversation, send a follow-up email as a formal request and so that you can provide all of the details they will need.

• What you are applying for
• Any requirements in content or format
• Timeline—your preferred timeline and/or the actual deadline
• How and/or where to submit the letter

Additional Suggestions

• Why you chose them as a recommender, either generally or for a specific program
• A copy of your resume
• A copy of items that speak to why you are applying, either for the field generally or for a specific program, such as a personal statement or application essay
• Anything else that helps

Request: Write a Letter of Recommendation

Dear _____________, I hope you are doing well. I wanted to let you know that I was really inspired after _____________, and it has led me to decide to pursue ___________. I am in the process of applying for ________. My application requires a recommendation letter from a ______ [their role: professor, former or current supervisor, etc.] and since __________ [the reason you are asking this person specifically], I was wondering if you would be willing to write a strong recommendation about me for my application. If so, the application is due __________, which allows four weeks to complete the letter. I would also be happy to meet with you if you would like to learn more about why I am applying to ____________ and what skills make me a good fit for it. Thank you in advance for your consideration, and I look forward to hearing back regarding your decision. Best, Your Name

After Asking

It is your job to prompt your recommender to write and submit the letter on time. If needed, send a gentle reminder a week before the deadline and ask if they need more information.

After your recommender submits the letter, be sure to follow up and thank them.

Follow-Up: Deadline Reminder

Dear _____________, Thank you again for agreeing to write a recommendation letter for my application to ________. I wanted to check in as the deadline is ________, just one week from today. Please let me know if there’s any additional information that would be helpful to you in writing the letter. Best, Your Name

Asking for Future Applications

If you think you might need letters of recommendation in the future, it is better to request them while you are still at BU and have good relationships with faculty or others you want to ask. Dossier service platforms like Interfolio will keep the letters confidential until you are ready for them to be submitted to an admissions or selection committee.

The essay underscores the significance of integers in fields like algebra, calculus, and computer science, illustrating their foundational role in both theoretical and practical mathematics.

How it works

Okay, imagine math without integers—it’s like trying to build a house without bricks! Integers are those whole numbers that can be positive, negative, or zero. They’re the backbone of math, used in everything from simple adding and subtracting to super complex theories.

Way back in ancient times, folks in Babylon and Egypt were already using integers to count stuff and do basic math. But the idea of negative numbers took a bit longer to catch on. It wasn’t until around the 7th century in India that people started using negative numbers in a more organized way.

A smarty pants named Brahmagupta figured out rules for dealing with negative numbers, which was a big deal.

Integers are super important in number theory, which is all about how numbers work together. There’s this famous thing called the Fundamental Theorem of Arithmetic, which says every number bigger than 1 can be broken down into prime numbers in a unique way. It’s like finding the secret code to unlock any number—it shows just how cool integers are in the math world.

You use integers all the time without even thinking about it. Like, when you talk about temperatures above or below zero, or when you deal with money—credits and debits are just positive and negative integers playing a money game. Even in games, when you go up or down levels based on how you play, that’s integers in action.

Now, when you add or subtract integers, you gotta pay attention to those plus and minus signs. Adding a positive number to a negative one means figuring out which number is bigger and using its sign for the answer. Multiplying and dividing integers also have their own special rules, especially when it comes to mixing positive and negative numbers together.

Zero is a special integer—it’s the only one that’s not positive or negative. It’s like the chill dude in the integer family. In addition, zero doesn’t change any number when you add it, and it makes any number zero when you multiply it. It’s kinda like the superhero of integers, keeping things balanced.

Integers aren’t just for simple math—they’re used in algebra, calculus, and even computer science. In algebra, they help solve equations and figure out patterns. And in computer stuff, integers are used to count things, organize data, and make programs run smoothly.

Understanding integers is key for anyone who loves math or works with numbers. They might seem simple, but they’re the foundation for so much cool math stuff. From ancient times to now, integers have been there, helping people understand the world through numbers.

Model of a massive particle in the dynamic medium of reference theory. Explanation of the wave-corpuscle duality and de Broglie wavelength

• Pignard, Olivier

The theory of the Dynamic Medium of Reference has already been presented in several articles, in particular O. Pignard, "Dynamic Medium of Reference: A new theory of gravitation" [Phys. Essays 32, 422 (2019)]. The objective of this article is to present a model of a massive particle within the framework of the Dynamic Medium of Reference theory. A concept of elementary wave on the subatomic level is introduced. An elementary wave is always identical to itself while being constantly renewed by new gravitons (entities that make up the medium of propagation of the wave). This elementary wave propagates in its medium (Dynamic Medium of Reference) at the speed of light, whatever its trajectory. A possible model of the elementary wave called vortex is presented in Appendix B. Then, the concept of line of vortices is introduced. The proposed model of a massive particle is then a set of lines of vortices. This model allows to explain that a massive particle has at the same time a wave aspect (because composed only of elementary waves) and a corpuscular aspect (since the elementary waves remain identical to themselves and that the massive particle remains delimited by the same volume). This model makes it possible to attribute to a massive particle a period T = γ ⋅ T 0 = T 0 / sin  , a pulsation or angular velocity Ω = ( Ω 0 / γ ) = Ω 0 sin  , an energy E = γ ⋅ m 0 c 0 2 = γ ⋅ E 0 = ( E O / sin  ) , and a momentum p = γ ⋅ m 0 V = ( m 0 c 0 / tan  ) , where T 0 , Ω 0 , E 0 , and m 0 are, respectively, the period, the pulsation, the energy, and the mass of the particle at rest in the Privileged Frame of Reference and  designates the angle defined by the relation cos  = V / c 0 , where V is the speed of the particle relative to the Privileged Frame of Reference. This same model also makes it possible to attribute to the massive particle the de Broglie wavelength of expression λ = ( h / p ) = λ 0 tan  with λ 0 = ( h / m 0 c 0 ) and a frequency of expression ν = ( c 0 / λ ) 2 + ( c 0 / λ 0 ) 2 = γ ⋅ ν 0 = ( ν 0 / sin  ) , where ν 0 = ( c 0 / λ 0 ) = ( m 0 c 0 2 / h ) represents the frequency of stationary elementary waves making circular revolutions when the particle is at rest in the Privileged Frame of Reference. Two types of configuration are considered for the particles of matter. In the first type of configuration, the lines of vortices are radial with a spherical envelope. This corresponds to particles of matter free in space, without any field. In the second type of configuration, the lines of vortices are parallel with a cylindrical envelope. This corresponds to nucleons (protons, neutrons) confined in an atomic nucleus by the strong force.

Citing a book chapter in apa.

To cite a book chapter , list information about the chapter first, followed by information about the book, including the book’s editor(s) and the chapter’s page range within the book.

The author of the chapter, not the editor of the book, is listed in the in-text citation.

Chicago notes and bibliography style uses footnotes to cite sources instead of parenthetical citations. These notes refer to a bibliography at the end giving full source details.

A Chicago bibliography entry for a book includes the author’s name, the book title and subtitle, the edition (if stated), the location and name of the publisher, and the year of publication. For an e-book , add the e-book format (e.g. “Kindle”) at the end.

Chicago also has an alternative style, Chicago author-date . You can see examples of book citations in this style here .

Citing a book chapter in Chicago

To cite a book chapter , start with the author and the title of the chapter (in quotation marks), then give the title (in italics) and editor of the book, the page range of the chapter, the location and name of the publisher, and the year of publication.

All the information you need for a book citation can usually be found on the book’s title page and copyright page. The main things you’re looking for are:

• the title (and subtitle if present)
• name(s) of the author(s)
• year of publication
• place of publication

You should also check if the book specifies an edition (e.g. 2nd edition, revised edition) and if any other contributors are named (e.g. editor, translator).

The image below shows where to find the relevant information on the title and copyright pages of a typical book.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

The main elements included in all book citations across APA , MLA , and Chicago style are the author, the title, the year of publication, and the name of the publisher. A page number is also included in in-text citations to highlight the specific passage cited.

In Chicago style and in the 6th edition of APA Style , the location of the publisher is also included, e.g. London: Penguin.

When a book’s chapters are written by different authors, you should cite the specific chapter you are referring to.

When all the chapters are written by the same author (or group of authors), you should usually cite the entire book, but some styles include exceptions to this.

• In APA Style , single-author books should always be cited as a whole, even if you only quote or paraphrase from one chapter.
• In MLA Style , if a single-author book is a collection of stand-alone works (e.g. short stories ), you should cite the individual work.
• In Chicago Style , you may choose to cite a single chapter of a single-author book if you feel it is more appropriate than citing the whole book.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

• APA Style is the most popular citation style, widely used in the social and behavioral sciences.
• MLA style is the second most popular, used mainly in the humanities.
• Chicago notes and bibliography style is also popular in the humanities, especially history.
• Chicago author-date style tends to be used in the sciences.

Other more specialized styles exist for certain fields, such as Bluebook and OSCOLA for law.

The most important thing is to choose one style and use it consistently throughout your text.

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

When you want to cite a specific passage in a source without page numbers (e.g. an e-book or website ), all the main citation styles recommend using an alternate locator in your in-text citation . You might use a heading or chapter number, e.g. (Smith, 2016, ch. 1)

In APA Style , you can count the paragraph numbers in a text to identify a location by paragraph number. MLA and Chicago recommend that you only use paragraph numbers if they’re explicitly marked in the text.

For audiovisual sources (e.g. videos ), all styles recommend using a timestamp to show a specific point in the video when relevant.

Opinion Justice Alito is right about today’s politics

America is in the middle of a nonmilitary civil war, and one side will win.

I don’t agree with Justice Samuel A. Alito Jr.’s stances on political and legal issues. Or on ethics. He should recuse himself from cases surrounding former president Donald Trump’s campaign. But he’s right about the divisions in our nation today — and I wish more liberals and moderates in powerful positions shared his perspective.

“One side or the other is going to win,” he told liberal filmmaker Lauren Windsor, who was posing as a conservative activist and secretly recording the conversation.

He added, “I don’t know. I mean, there can be a way of working — a way of living together peacefully, but it’s difficult, you know, because there are differences on fundamental things that really can’t be compromised. They really can’t be compromised. So it’s not like you are going to split the difference.” The comments were first reported by Rolling Stone .

Today’s fissure between liberals/Democrats/blue states and conservatives/Republicans/red states is deep and, as Alito says, in some ways intractable. The average voter in California does not have totally different views from the average voter in Wyoming. But white Christian nationalist, anti-critical race theory, anti-transgender activists and voters in Texas do hold views that are irreconcilable with those of New York leftists who believe that colonialism, patriarchy and white supremacy are the foundations on which America has been built.

We are not just in a “culture war” over whether people should read the New York Times’s 1619 Project or use the term “Latinx.” States run by Republicans make it very difficult to join a labor union or have an abortion. They strip power from liberal elected officials and sometimes remove them from office . A person with views shared by many White born-again Christians (opposition to abortion and gender-affirming care , that Black people would be as well off as White people on average if they worked harder ) will almost never be elected to a powerful job in a blue state.

Most important, key figures who shape Republican Party policy act as though conservatives are in an existential war with the left. That includes Florida Gov. Ron DeSantis , Justice Clarence Thomas, activist Christopher Rufo and Trump advisers Russ Vought and Stephen Miller. If Trump returns to the White House, he has made clear that his administration would treat federal workers, left-wing college professors and students, and others whom conservatives don’t like as enemies of the state.

I don’t want Democratic officials, news outlets, nonprofits or other nonconservatives to take actions as radical as these Republicans. The Biden administration should not list groups it would target if the president were to win a second term.

But I wish powerful institutions and individuals on the left and center understood that the country is in the middle of a nonmilitary civil war and acted with the focus and purpose that such a belief would entail.

You might say many people are treating the prospect of Trump winning in November with alarm. That’s true. But the problem isn’t just Trump. The banning of abortion in many states, diminishment of the Voting Rights Act , rollback of state criminal justice reforms and enactment of widespread restrictions on talking about race in public schools and colleges all happened over the past three years while Trump held no office. Conservative activists and officials are daily attacking left-wing institutions and values. They use whatever power they have, from the Republican-dominated courts to state legislatures to congressional hearings, which led to the resignations of the presidents of Harvard and the University of Pennsylvania.

Alito’s framing, with the use of the term “side,” was exactly right. There is a conservative side, much broader than just Trump alone. And it is looking to win, not compromise. Abortion was already pretty restricted in red states in 2021. But conservatives still pushed to get Roe v. Wade overturned — and did.

In contrast, Democrats act as though they are in a fight with Trump alone. In 2021, even as the Supreme Court was becoming more radical, Biden not only took the weakest approach possible (appointing a commission to study the issue) but also basically ignored its findings. He bragged about the relatively toothless gun-control bill he passed with Republicans in Washington, ignoring how state-level conservatives were weakening restrictions on gun rights in much of the country.

Senate Judiciary Chairman Dick Durbin (D-Ill.) refuses to even hold hearings about the controversies surrounding Alito and Thomas.

Many news organizations, including some liberal ones, depict politics as Trump vs. D.C. Democrats . They barely cover state politics, essentially ignoring where much political action takes place. The media still often grades politicians’ effectiveness based on their ability to work across party lines. But Republicans such as Vought accomplish their goals without any support from liberals.

I can’t prove that prominent Democratic politicians and other prominent figures on the center and left have a different perspective from Alito’s. Perhaps in private they too recognize that the country is in a deep conflict that one side has to win. I assume Biden supporters would argue that the president recognizes the deeper divide but thinks that the best way to address it is for him to win reelection, in part by being more conciliatory.

Here’s why I’m skeptical of that view. Democrats in very blue areas, such as Durbin, who don’t have to woo Republican voters, still don’t act with much urgency. They behave as though reaching an agreement with a conservative lawmaker is a huge achievement.

The media seem constantly surprised by the extremist actions of the Republican Party, such as nominating Trump for president again. But it’s not shocking that a political movement that believes it’s in a life-or-death struggle remains behind a man who has shown both deep commitments to the movement’s causes and a willingness to use any means necessary to win political fights.

There are two visions of America being advanced. Liberals are willing to compromise on some parts of theirs, but the most powerful conservatives aren’t looking to meet in the middle. The best way to lose a battle is to pretend it’s not happening — and unfortunately that’s what many prominent liberals and moderates are doing.
