How to Cite a Website

Last Updated: February 9, 2023 Fact Checked

This article was co-authored by Michelle Golden, PhD and by wikiHow staff writer, Jennifer Mueller, JD . Michelle Golden is an English teacher in Athens, Georgia. She received her MA in Language Arts Teacher Education in 2008 and received her PhD in English from Georgia State University in 2015. There are 7 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 3,558,795 times.

If you're writing a research paper, you'll likely do quite a bit of research online. If you have websites that you want to use as sources for your paper, an entry for the website must appear in the reference list (also called the bibliography or Works Cited) at the end of your paper. You'll also include a citation in-text at the end of any sentence in which you've paraphrased or quoted information that appeared on that website. While the information you need to provide is generally the same across all methods, the way you format that information may vary depending on whether you're using the Modern Language Association (MLA), American Psychological Association (APA), or Chicago style of citation.

Sample Citation Templates

• Example: Claymore, Crystal.
• If no individual author is listed, but the website is produced by a government agency, organization, or business, use that name as the author. For example, if you're using a CDC web page as a source, you would list the author as "Centers for Disease Control and Prevention."

Tip: For your entire Works Cited entry, if an element doesn't exist or isn't provided, simply skip that part of the citation and move on to the next part.

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting."

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , 24 Sept. 2018,

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , 24 Sept. 2018, www.crystalscupcakes.com/amazing-frosting.

• Example: Claymore, Crystal. "Best-Kept Secrets for Amazing Cupcake Frosting." Crystal's Cupcakes , www.crystalscupcakes.com/amazing-frosting. Accessed 14 Feb. 2019.

MLA Works Cited Format:

Author Last Name, First Name. "Title of Web Page in Title Case." Name of Website , Day Month Year of publication, URL. Accessed Day Month Year.

• For example, you might write: "The best cupcake frosting techniques are often the least intuitive (Claymore)."
• If you include the author's name in your text, there's no need for a parenthetical citation. For example, you might write: "Award-winning baker Crystal Claymore wasn't afraid to give away all her secrets, sharing her favorite frosting techniques on her website."

• Example: Canadian Cancer Society.

• Example: Canadian Cancer Society. (2017).
• If you're citing several pages from the same website that were published in the same year, add a lower-case letter to the end of the year so you can differentiate them in your in-text citations. For example, you might have "2017a" and "2017b."

• Example: Canadian Cancer Society. (2017). Cancer research.
• If the content you're citing is a stand-alone document, the title should be italicized. This will usually be the case if you're citing a PDF document that appears on a website. If you're not sure, use your best judgment in deciding whether to italicize it or not.

• Example: Canadian Cancer Society. (2017). Cancer research. Retrieved from http://www.cancer.ca/en/cancer-information/cancer-101/cancer-research/?region=on

APA Reference List Format:

Author Last Name, A. A. (Year). Title of web page in sentence case. Retrieved from URL

• For example, you might write: "Clinical trials are used to test new cancer treatments (Canadian Cancer Society, 2017)."
• If you include the author's name in your text, place the year in parentheses immediately after the author's name. For example, you might write: "The Canadian Cancer Society (2017) noted that Canada is a global leader in clinical trials of cancer treatments."

• Example: UN Women.

• Example: UN Women. "Commission on the Status of Women."

• Example: UN Women. "Commission on the Status of Women." UN Women .

• Example: UN Women. "Commission on the Status of Women." UN Women . Accessed February 14, 2019.

• Example: UN Women. "Commission on the Status of Women." UN Women . Accessed February 14, 2019. http://www.unwomen.org/en/csw.

Chicago Bibliography Format:

Author Last Name, First Name. "Title of Web Page in Title Case." Name of Website or Publishing Organization . Accessed Month Day, Year. URL.

• Example: UN Women, "Commission on the Status of Women," UN Women , accessed February 14, 2019, http://www.unwomen.org/en/csw.

Reference a Website in Harvard Style | Templates & Examples

Published on 19 May 2020 by Jack Caulfield . Revised on 7 November 2022.

To reference a website in Harvard style , include the name of the author or organization, the year of publication, the title of the page, the URL, and the date on which you accessed the website.

Different formats are used for other kinds of online source, such as articles, social media posts and multimedia content. You can generate accurate Harvard references for all kinds of sources with our free reference generator:

Table of contents

Online articles, social media posts, images, videos and podcasts, referencing websites with missing information, frequently asked questions about harvard website references.

Blog posts and online newspaper articles are both referenced in the same format: include the title of the article in quotation marks, the name of the blog or newspaper in italics, and the date of publication.

The format for a magazine article is slightly different. Instead of a precise date, include the month, season, or volume and issue number, depending on what the magazine uses to identify its issues.

The URL and access date information are included only when the article is online-exclusive.

To reference posts from social media platforms like Facebook, Twitter and Instagram, include the username and the platform in square brackets. Write usernames the way they appear on the platform, with the same capitalization and symbols.

If the post has a title, use it (in quotation marks). If the post is untitled, use the text of the post instead. Do not use italics. If the text is long, you can replace some of it with an ellipsis.

Online content is referenced differently if it is in video, audio or image form.

To cite an image found online, such as an artwork, photograph, or infographic, include the image format (e.g. ‘Photograph’, ‘Oil on canvas’) in square brackets.

Online videos, such as those on YouTube, Instagram, Vimeo and Dailymotion, are cited similarly to general web pages. Where a video is uploaded under the name of an individual, write the name in the usual format. Otherwise, write the username of the uploader as it appears on the site.

If you want to locate a specific point in a video in an in-text citation, you can do so using a timestamp.

For a podcast reference, you just need the name of the individual episode, not of the whole series. The word ‘Podcast’ is always included in square brackets. As with videos, you can use a timestamp to locate a specific point in the in-text citation.

Online sources are often missing information you would usually need for a citation: author, title or date. Here’s what to do when these details are not available.

When a website doesn’t list a specific individual author, you can usually find a corporate author to list instead. This is the organisation responsible for the source:

In cases where there’s no suitable corporate author (such as online dictionaries or Wikis), use the title of the source in the author position instead:

In Harvard style, when a source doesn’t list a specific date of publication, replace it with the words ‘no date’ in both the in-text citation and the reference list. You should still include an access date:

Prevent plagiarism, run a free check.

It’s important to assess the reliability of information found online. Look for sources from established publications and institutions with expertise (e.g. peer-reviewed journals and government agencies).

The CRAAP test (currency, relevance, authority, accuracy, purpose) can aid you in assessing sources, as can our list of credible sources . You should generally avoid citing websites like Wikipedia that can be edited by anyone – instead, look for the original source of the information in the “References” section.

You can generally omit page numbers in your in-text citations of online sources which don’t have them. But when you quote or paraphrase a specific passage from a particularly long online source, it’s useful to find an alternate location marker.

For text-based sources, you can use paragraph numbers (e.g. ‘para. 4’) or headings (e.g. ‘under “Methodology”’). With video or audio sources, use a timestamp (e.g. ‘10:15’).

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

Digital Citations: A comprehensive guide to citing of websites in APA, MLA, and CMOS style

In today’s digital age, the internet serves as an invaluable resource for researchers across all disciplines. As the digital knowledge repository continues to expand, citing websites has become an integral aspect of academic writing. However, scholars, from undergraduates to seasoned researchers, often find themselves grappled with the intricacies of citing online sources. In this article, we will explore the importance of digital citations and delve into the nuances of citing websites in different citation styles.

Table of Contents

Why Cite Websites?

In recent years, the reliance of online resources has surged in parallel to the exponential growth of the internet. From scholarly articles and reports to blog posts and social media threads, researchers frequently rely on web sources to support their arguments and findings. As a result, the increasing amount of data online in various websites has become an integral part of academic writing across disciplines. From scholarly articles to dissertations , researchers frequently refer online sources to stay updated on the latest research.

Moreover, citing websites enhances a researcher’s visibility by linking their work to a broader digital landscape, potentially increasing its impact and facilitating collaboration. Although citing websites is essential for effectively communicating one’s research in today’s digital landscape, finding the right website is essential to find reliable information.

Identifying the Right Websites

Identifying reliable and credible websites is paramount when gathering information for academic purposes. To ensure the quality and accuracy of your sources, consider the following tips:

1. Evaluate the Domain

Websites ending in .gov, .edu, or .org are often more credible for academic research data

2. Assess the Authorship

Look for the credentials and information about the author or organization responsible for the content

3. Verify the Content Accuracy

Evaluate the timeline and accuracy by cross-referring other reliable sources of information

4. Check for Citations

Reliable websites often cite their sources, providing a trail of evidence to support their claims

Taking time to thoroughly gauge website quality on the above criteria goes a long way in boosting scholarly impact and confidence in the evidence you bring to support arguments upon which you cite them. Additionally, the reliability of your sources directly correlates with the academic strength of your work.

Components of Website Citations

In academic writing, website citations typically include the following components:

Citing a Website in APA, MLA and CMOS Style

Citing a website in the required style can boost the academic tone. There are several styles of citing a website. Citing websites correctly is essential to adhere to the citation guidelines mentioned by your institution.

Here’s how to cite a website in APA (American Psychological Association), MLA (Modern Language Association), and Chicago styles to ensure that your research papers and articles are accurately documented and credible for your readers.

1. APA Style

Includes: Author’s last name, initials. (full date of publication – Year Month Day). title of the webpage (in italics). website name (in plain text). URL of the website

In-text citation: Author, Year

Example: Nair, Anagha. (2024, February 22). Plain Language Summary — Communicating your research to bridge the academic-lay gap. Enago Academy. https://www.enago.com/academy/plain-language-summary/

(It is important to note that the name of the blog posts is italicized while citing blogs and articles.)

2. MLA Style

Includes: Author last name, first name. “title of the webpage.” website name (in italics), accessed date (Day Month Year), URL of the website

In-text citation:  Name of the website

Example of citing a webpage: Nair, Anagha. “Plain Language Summary — Communicating your research to bridge the academic-lay gap.” Enago Academy , 22 February 2024, https://www.enago.com/academy/plain-language-summary/

3. Chicago Style

Includes: Author last name, first name. “title of the webpage.” website name (in italics), accessed date (Month Day, Year). URL of the website

In-text citation: (Author Year)

Example: Nair, Anagha. Plain Language Summary — Communicating your research to bridge the academic-lay gap. Enago Academy , February 22, 2024. https://www.enago.com/academy/plain-language-summary/

When a page has no author specified, you can mention the name of the organization that created it instead. However, this can be avoided if matches to the name of the website.  Furthermore, if the date of publication is not available, “n.d.” can be used in its place. You can also include an access date (depending upon the citation style)

Understanding different citation styles when citing websites is important as it shows you understand academic conventions and demonstrates your ability to pay attention to important formatting details. Instead of citing manually, one can use citation generator tools to generate citation. Furthermore, using tools such as Enago Plagiarism Checker can help in improving your written work by detecting plagiarism, improving grammar and generate citation.

Here’s a step-by-step guide on how to cite a website properly in your research papers and articles.

It is important to note that some styles, like APA, may require you to include the date you accessed the webpage, especially for dynamic or frequently updated content. Furthermore, it was advisable to include DOI (Digital Object Identifier) or a stable permalink in your citation, if provided by the website, for better accessibility.

Difference Between Citing a Website and Research Papers

While citing websites shares similarities with citing research papers from journals, there are some notable differences. Websites often lack formal publication information such as volume and issue numbers, making it essential to include additional details like the URL and access date in certain citation styles. Moreover, websites may vary widely in terms of reliability and credibility, necessitating a more critical evaluation of sources.

Citing websites can improve the impact and credibility of your work. Are you a researcher struggling to cast an impact with your research? Consider Enago’s Research Impact Services to allow a team of industry experts assist your publishing journey!

Mastering the art of citing websites is essential for researchers at all stages of their academic journey. By citing sources accurately, identifying credible websites, and adhering to established citation styles, researchers can enhance the credibility and impact of their work in the digital age.

Cite a Website

Don't let plagiarism errors spoil your paper, citing a website in apa.

Once you’ve identified a credible website to use, create a citation and begin building your reference list. Citation Machine citing tools can help you create references for online news articles, government websites, blogs, and many other website! Keeping track of sources as you research and write can help you stay organized and ethical. If you end up not using a source, you can easily delete it from your bibliography. Ready to create a citation? Enter the website’s URL into the search box above. You’ll get a list of results, so you can identify and choose the correct source you want to cite. It’s that easy to begin!

If you’re wondering how to cite a website in APA, use the structure below.

Author Last Name, First initial. (Year, Month Date Published). Title of web page . Name of Website. URL

Example of an APA format website:

Austerlitz, S. (2015, March 3). How long can a spinoff like ‘Better Call Saul’ last? FiveThirtyEight. http://fivethirtyeight.com/features/how-long-can-a-spinoff-like-better-call-saul-last/

Keep in mind that not all information found on a website follows the structure above. Only use the Website format above if your online source does not fit another source category. For example, if you’re looking at a video on YouTube, refer to the ‘YouTube Video’ section. If you’re citing a newspaper article found online, refer to ‘Newspapers Found Online’ section. Again, an APA website citation is strictly for web pages that do not fit better with one of the other categories on this page.

Social media:

When adding the text of a post, keep the original capitalization, spelling, hashtags, emojis (if possible), and links within the text.

Facebook posts:

Structure: Facebook user’s Last name, F. M. (Year, Monday Day of Post). Up to the first 20 words of Facebook post [Source type if attached] [Post type]. Facebook. URL

Source type examples: [Video attached], [Image attached]

Post type examples: [Status update], [Video], [Image], [Infographic]

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.

• Book Chapter
• Conference Paper
• Documentary
• Encyclopedia
• Google Images
• Kindle Book
• Memorial Inscription
• Museum Exhibit
• Painting or Artwork
• PowerPoint Presentation
• Sheet Music
• Thesis or Dissertation
• YouTube Video

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.

Research Paper Citation

Research paper citation refers to the act of acknowledging and referencing a previously published work in a scholarly or academic paper . When citing sources, researchers provide information that allows readers to locate the original source, validate the claims or arguments made in the paper, and give credit to the original author(s) for their work.

The citation may include the author’s name, title of the publication, year of publication, publisher, and other relevant details that allow readers to trace the source of the information. Proper citation is a crucial component of academic writing, as it helps to ensure accuracy, credibility, and transparency in research.

Purpose of Research Paper Citation

The purpose of citing sources in a research paper is to give credit to the original authors and acknowledge their contribution to your work. By citing sources, you are also demonstrating the validity and reliability of your research by showing that you have consulted credible and authoritative sources. Citations help readers to locate the original sources that you have referenced and to verify the accuracy and credibility of your research. Additionally, citing sources is important for avoiding plagiarism, which is the act of presenting someone else’s work as your own. Proper citation also shows that you have conducted a thorough literature review and have used the existing research to inform your own work. Overall, citing sources is an essential aspect of academic writing and is necessary for building credibility, demonstrating research skills, and avoiding plagiarism.

Advantages of Research Paper Citation

There are several advantages of research paper citation, including:

• Giving credit: By citing the works of other researchers in your field, you are acknowledging their contribution and giving credit where it is due.
• Strengthening your argument: Citing relevant and reliable sources in your research paper can strengthen your argument and increase its credibility. It shows that you have done your due diligence and considered various perspectives before drawing your conclusions.
• Demonstrating familiarity with the literature : By citing various sources, you are demonstrating your familiarity with the existing literature in your field. This is important as it shows that you are well-informed about the topic and have done a thorough review of the available research.
• Providing a roadmap for further research: By citing relevant sources, you are providing a roadmap for further research on the topic. This can be helpful for future researchers who are interested in exploring the same or related issues.
• Building your own reputation: By citing the works of established researchers in your field, you can build your own reputation as a knowledgeable and informed scholar. This can be particularly helpful if you are early in your career and looking to establish yourself as an expert in your field.

Citing Sources: What are citations and why should I use them?

What is a citation.

Citations are a way of giving credit when certain material in your work came from another source. It also gives your readers the information necessary to find that source again-- it provides an important roadmap to your research process. Whenever you use sources such as books, journals or websites in your research, you must give credit to the original author by citing the source. 

Why do researchers cite?

Scholarship is a conversation  and scholars use citations not only to  give credit  to original creators and thinkers, but also to  add strength and authority  to their own work.  By citing their sources, scholars are  placing their work in a specific context  to show where they “fit” within the larger conversation.  Citations are also a great way to  leave a trail  intended to help others who may want to explore the conversation or use the sources in their own work.

In short, citations

(1) give credit

(2) add strength and authority to your work

(3) place your work in a specific context

(4) leave a trail for other scholars

"Good citations should reveal your sources, not conceal them. They should honeslty reflect the research you conducted." (Lipson 4)

Lipson, Charles. "Why Cite?"  Cite Right: A Quick Guide to Citation Styles--MLA, APA, Chicago, the Sciences, Professions, and More . Chicago: U of Chicago, 2006. Print.

What does a citation look like?

Different subject disciplines call for citation information to be written in very specific order, capitalization, and punctuation. There are therefore many different style formats. Three popular citation formats are MLA Style (for humanities articles) and APA or Chicago (for social sciences articles).

MLA style (print journal article):  

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles Vol. 49.3 (2003): 179-182.

APA style (print journal article):

Whisenant, W. A. (2003) How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX. Sex Roles , 49 (3), 179-182.

Chicago style (print journal article):

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles 49, no. 3 (2003): 179-182.

No matter which style you use, all citations require the same basic information:

• Author or Creator
• Container (e.g., Journal or magazine, website, edited book)
• Date of creation or publication
• Publisher 

You are most likely to have easy access to all of your citation information when you find it in the first place. Take note of this information up front, and it will be much easier to cite it effectively later.

Bibliometrics Overview

Welcome to Purdue University's Citation Databases Research Guide

Here you will find...

• Information on citation databases
• Descriptions of these databases
• Helpful examples on how to use them
• Use cases for each of the major citation databases
• Useful tips and tricks on how to best make use of them

Here are some definitions of common terms made use of by citation databases

• Bibliometrics is the statistical analysis of scholarly output like articles, book chapters, and reviews.
• Altmetrics: is the statistical analysis of alternative forms of capture such as twitter impressions of a piece of scholarly output.

Some common metrics are the H-index, Journal Impact Factor, and the FWCI (called CNCI in Web of Science).

• H-Index is a measure of how many times a journals published articles are cited, an index of fifteen means an article has been cited 15 times.
• Journal Impact Factor (IF) – A measurement of how many times a journal’s published articles are cited by different researchers.
• FWCI – Publication Field weighted citation indices indicate how the number of citations received by researcher’s publications compared to the average number for similar publications.
• Category Normalized Citation Impact (CNCI) – Calculated using Web of Science, CNCI is “an indicator of impact normalized for subject focus, age and document type. A CNCI of 1 is at par with the world average, anything above 2 is twice the global average
• SJR - Scimago Journal Rank is a measure of the "prestige" of journals which makes use of both the number of citations a journal accrues and the perception of those journals in the wider academic community
• SNIP - Source Normalized Impact per Paper is a metric which accounts for the field specific differences between journals. The need for this is that some fields have different publishing practices, time frames, and constraints. This results in the need for a metric like SNIP which is calculated by comparing the citations per journal with the citation potential of the field as a whole, in other words it would measure of history journal against other history journals and vice versa for other academic disciplines

Here are the five most common Citation Databases' Key Strengths and Use Cases

• Web of Science: Core Collection Access the world’s leading scholarly literature in the sciences, social sciences, arts, and humanities and examine proceedings of international conferences, symposia, seminars, colloquia, workshops, and conventions. -Science Citation Index Expanded (1900-present) -Social Sciences Citation Index (1900-present) -Arts & Humanities Citation Index (1975-present) -Conference Proceedings Citation Index- Science (1990-present) -Conference Proceedings Citation Index- Social Science & Humanities (1990-present) -Book Citation Index– Science (2005-present) -Book Citation Index– Social Sciences & Humanities (2005-present) -Current Chemical Reactions (1985-present) (Includes Institut National de la Propriete Industrielle structure data back to 1840) -Index Chemicus (1993-present) -Emerging Sources Citation Index (2005 – present)
• Google Scholar Searches for scholarly materials such as peer-reviewed papers, theses, books, preprints, abstracts and technical reports from broad areas of research. It includes a variety of academic publishers, professional societies, preprint repositories and universities, as well as scholarly articles available across the web.
• Dimensions Dimensions is a citations database which specializes in providing abstracts, citations, and patents to users. While the Library does not currently subscribe, you can access the free version of the database from this link

Revealed: the ten research papers that policy documents cite most

Policymakers often work behind closed doors — but the documents they produce offer clues about the research that influences them. Credit: Stefan Rousseau/Getty

When David Autor co-wrote a paper on how computerization affects job skill demands more than 20 years ago, a journal took 18 months to consider it — only to reject it after review. He went on to submit it to The Quarterly Journal of Economics , which eventually published the work 1 in November 2003.

Autor’s paper is now the third most cited in policy documents worldwide, according to an analysis of data provided exclusively to Nature . It has accumulated around 1,100 citations in policy documents, show figures from the London-based firm Overton (see ‘The most-cited papers in policy’), which maintains a database of more than 12 million policy documents, think-tank papers, white papers and guidelines.

“I thought it was destined to be quite an obscure paper,” recalls Autor, a public-policy scholar and economist at the Massachusetts Institute of Technology in Cambridge. “I’m excited that a lot of people are citing it.”

The most-cited papers in policy

Economics papers dominate the top ten papers that policy documents reference most.

Data from Sage Policy Profiles as of 15 April 2024

The top ten most cited papers in policy documents are dominated by economics research. When economics studies are excluded, a 1997 Nature paper 2 about Earth’s ecosystem services and natural capital is second on the list, with more than 900 policy citations. The paper has also garnered more than 32,000 references from other studies, according to Google Scholar. Other highly cited non-economics studies include works on planetary boundaries, sustainable foods and the future of employment (see ‘Most-cited papers — excluding economics research’).

These lists provide insight into the types of research that politicians pay attention to, but policy citations don’t necessarily imply impact or influence, and Overton’s database has a bias towards documents published in English.

Interdisciplinary impact

Overton usually charges a licence fee to access its citation data. But last year, the firm worked with the London-based publisher Sage to release a free web-based tool that allows any researcher to find out how many times policy documents have cited their papers or mention their names. Overton and Sage said they created the tool, called Sage Policy Profiles, to help researchers to demonstrate the impact or influence their work might be having on policy. This can be useful for researchers during promotion or tenure interviews and in grant applications.

Autor thinks his study stands out because his paper was different from what other economists were writing at the time. It suggested that ‘middle-skill’ work, typically done in offices or factories by people who haven’t attended university, was going to be largely automated, leaving workers with either highly skilled jobs or manual work. “It has stood the test of time,” he says, “and it got people to focus on what I think is the right problem.” That topic is just as relevant today, Autor says, especially with the rise of artificial intelligence.

Most-cited papers — excluding economics research

When economics studies are excluded, the research papers that policy documents most commonly reference cover topics including climate change and nutrition.

Walter Willett, an epidemiologist and food scientist at the Harvard T.H. Chan School of Public Health in Boston, Massachusetts, thinks that interdisciplinary teams are most likely to gain a lot of policy citations. He co-authored a paper on the list of most cited non-economics studies: a 2019 work 3 that was part of a Lancet commission to investigate how to feed the global population a healthy and environmentally sustainable diet by 2050 and has accumulated more than 600 policy citations.

“I think it had an impact because it was clearly a multidisciplinary effort,” says Willett. The work was co-authored by 37 scientists from 17 countries. The team included researchers from disciplines including food science, health metrics, climate change, ecology and evolution and bioethics. “None of us could have done this on our own. It really did require working with people outside our fields.”

Sverker Sörlin, an environmental historian at the KTH Royal Institute of Technology in Stockholm, agrees that papers with a diverse set of authors often attract more policy citations. “It’s the combined effect that is often the key to getting more influence,” he says.

Sörlin co-authored two papers in the list of top ten non-economics papers. One of those is a 2015 Science paper 4 on planetary boundaries — a concept defining the environmental limits in which humanity can develop and thrive — which has attracted more than 750 policy citations. Sörlin thinks one reason it has been popular is that it’s a sequel to a 2009 Nature paper 5 he co-authored on the same topic, which has been cited by policy documents 575 times.

Although policy citations don’t necessarily imply influence, Willett has seen evidence that his paper is prompting changes in policy. He points to Denmark as an example, noting that the nation is reformatting its dietary guidelines in line with the study’s recommendations. “I certainly can’t say that this document is the only thing that’s changing their guidelines,” he says. But “this gave it the support and credibility that allowed them to go forward”.

Broad brush

Peter Gluckman, who was the chief science adviser to the prime minister of New Zealand between 2009 and 2018, is not surprised by the lists. He expects policymakers to refer to broad-brush papers rather than those reporting on incremental advances in a field.

Gluckman, a paediatrician and biomedical scientist at the University of Auckland in New Zealand, notes that it’s important to consider the context in which papers are being cited, because studies reporting controversial findings sometimes attract many citations. He also warns that the list is probably not comprehensive: many policy papers are not easily accessible to tools such as Overton, which uses text mining to compile data, and so will not be included in the database.

The top 100 papers

“The thing that worries me most is the age of the papers that are involved,” Gluckman says. “Does that tell us something about just the way the analysis is done or that relatively few papers get heavily used in policymaking?”

Gluckman says it’s strange that some recent work on climate change, food security, social cohesion and similar areas hasn’t made it to the non-economics list. “Maybe it’s just because they’re not being referred to,” he says, or perhaps that work is cited, in turn, in the broad-scope papers that are most heavily referenced in policy documents.

As for Sage Policy Profiles, Gluckman says it’s always useful to get an idea of which studies are attracting attention from policymakers, but he notes that studies often take years to influence policy. “Yet the average academic is trying to make a claim here and now that their current work is having an impact,” he adds. “So there’s a disconnect there.”

Willett thinks policy citations are probably more important than scholarly citations in other papers. “In the end, we don’t want this to just sit on an academic shelf.”

Title: research on detection of floating objects in river and lake based on ai intelligent image recognition.

Abstract: With the rapid advancement of artificial intelligence technology, AI-enabled image recognition has emerged as a potent tool for addressing challenges in traditional environmental monitoring. This study focuses on the detection of floating objects in river and lake environments, exploring an innovative approach based on deep learning. By intricately analyzing the technical pathways for detecting static and dynamic features and considering the characteristics of river and lake debris, a comprehensive image acquisition and processing workflow has been developed. The study highlights the application and performance comparison of three mainstream deep learning models -SSD, Faster-RCNN, and YOLOv5- in debris identification. Additionally, a detection system for floating objects has been designed and implemented, encompassing both hardware platform construction and software framework development. Through rigorous experimental validation, the proposed system has demonstrated its ability to significantly enhance the accuracy and efficiency of debris detection, thus offering a new technological avenue for water quality monitoring in rivers and lakes

MLA In-Text Citations: The Basics

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Guidelines for referring to the works of others in your text using MLA style are covered throughout the  MLA Handbook  and in chapter 7 of the  MLA Style Manual . Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA Style, referring to the works of others in your text is done using parenthetical citations . This method involves providing relevant source information in parentheses whenever a sentence uses a quotation or paraphrase. Usually, the simplest way to do this is to put all of the source information in parentheses at the end of the sentence (i.e., just before the period). However, as the examples below will illustrate, there are situations where it makes sense to put the parenthetical elsewhere in the sentence, or even to leave information out.

General Guidelines

• The source information required in a parenthetical citation depends (1) upon the source medium (e.g. print, web, DVD) and (2) upon the source’s entry on the Works Cited page.
• Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text must be the first thing that appears on the left-hand margin of the corresponding entry on the Works Cited page.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads . Oxford UP, 1967.

In-text citations for print sources with known author

For print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry on the Works Cited page:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method . University of California Press, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for sources with non-standard labeling systems

If a source uses a labeling or numbering system other than page numbers, such as a script or poetry, precede the citation with said label. When citing a poem, for instance, the parenthetical would begin with the word “line”, and then the line number or range. For example, the examination of William Blake’s poem “The Tyger” would be cited as such:

The speaker makes an ardent call for the exploration of the connection between the violence of nature and the divinity of creation. “In what distant deeps or skies. / Burnt the fire of thine eyes," they ask in reference to the tiger as they attempt to reconcile their intimidation with their relationship to creationism (lines 5-6).

Longer labels, such as chapters (ch.) and scenes (sc.), should be abbreviated.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name, following these guidelines.

Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

Titles longer than a standard noun phrase should be shortened into a noun phrase by excluding articles. For example, To the Lighthouse would be shortened to Lighthouse .

If the title cannot be easily shortened into a noun phrase, the title should be cut after the first clause, phrase, or punctuation:

In this example, since the reader does not know the author of the article, an abbreviated title appears in the parenthetical citation, and the full title of the article appears first at the left-hand margin of its respective entry on the Works Cited page. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs . 1999. www.climatehotmap.org/. Accessed 23 Mar. 2009.

If the title of the work begins with a quotation mark, such as a title that refers to another work, that quote or quoted title can be used as the shortened title. The single quotation marks must be included in the parenthetical, rather than the double quotation.

Parenthetical citations and Works Cited pages, used in conjunction, allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work, like Marx and Engels's  The Communist Manifesto . In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Author-page citation for works in an anthology, periodical, or collection

When you cite a work that appears inside a larger source (for instance, an article in a periodical or an essay in a collection), cite the author of the  internal source (i.e., the article or essay). For example, to cite Albert Einstein's article "A Brief Outline of the Theory of Relativity," which was published in  Nature  in 1921, you might write something like this:

See also our page on documenting periodicals in the Works Cited .

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Corresponding Works Cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations , vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine , vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by an author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author :

Citing two books by the same author :

Additionally, if the author's name is not mentioned in the sentence, format your citation with the author's name followed by a comma, followed by a shortened title of the work, and, when appropriate, the page number(s):

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter, and verse. For example:

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation:

John of Patmos echoes this passage when describing his vision (Rev. 4.6-8).

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited within another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing transcripts, plays, or screenplays

Sources that take the form of a dialogue involving two or more participants have special guidelines for their quotation and citation. Each line of dialogue should begin with the speaker's name written in all capitals and indented half an inch. A period follows the name (e.g., JAMES.) . After the period, write the dialogue. Each successive line after the first should receive an additional indentation. When another person begins speaking, start a new line with that person's name indented only half an inch. Repeat this pattern each time the speaker changes. You can include stage directions in the quote if they appear in the original source.

Conclude with a parenthetical that explains where to find the excerpt in the source. Usually, the author and title of the source can be given in a signal phrase before quoting the excerpt, so the concluding parenthetical will often just contain location information like page numbers or act/scene indicators.

Here is an example from O'Neill's  The Iceman Cometh.

WILLIE. (Pleadingly) Give me a drink, Rocky. Harry said it was all right. God, I need a drink.

ROCKY. Den grab it. It's right under your nose.

WILLIE. (Avidly) Thanks. (He takes the bottle with both twitching hands and tilts it to his lips and gulps down the whiskey in big swallows.) (1.1)

Citing non-print or sources from the Internet

With more and more scholarly work published on the Internet, you may have to cite sources you found in digital environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's  Evaluating Sources of Information  resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source on your Works Cited page.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers. However, these sorts of entries often do not require a page number in the parenthetical citation. For electronic and Internet sources, follow the following guidelines:

• Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
• Do not provide paragraph numbers or page numbers based on your Web browser’s print preview function.
• Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like  CNN.com  or  Forbes.com,  as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Two types of non-print sources you may encounter are films and lectures/presentations:

In the two examples above “Herzog” (a film’s director) and “Yates” (a presentor) lead the reader to the first item in each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo . Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002. Address.

Electronic sources

Electronic sources may include web pages and online news or magazine articles:

In the first example (an online magazine article), the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below).

In the second example (a web page), a parenthetical citation is not necessary because the page does not list an author, and the title of the article, “MLA Formatting and Style Guide,” is used as a signal phrase within the sentence. If the title of the article was not named in the sentence, an abbreviated version would appear in a parenthetical citation at the end of the sentence. Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant , 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/. Accessed 29 Sep. 2009. 

"MLA Formatting and Style Guide." The Purdue OWL , 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/. Accessed 2 April 2018.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference. For example: (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations, or common knowledge (For example, it is expected that U.S. citizens know that George Washington was the first President.). Remember that citing sources is a rhetorical task, and, as such, can vary based on your audience. If you’re writing for an expert audience of a scholarly journal, for example, you may need to deal with expectations of what constitutes “common knowledge” that differ from common norms.

Other Sources

The MLA Handbook describes how to cite many different kinds of authors and content creators. However, you may occasionally encounter a source or author category that the handbook does not describe, making the best way to proceed can be unclear.

In these cases, it's typically acceptable to apply the general principles of MLA citation to the new kind of source in a way that's consistent and sensible. A good way to do this is to simply use the standard MLA directions for a type of source that resembles the source you want to cite.

You may also want to investigate whether a third-party organization has provided directions for how to cite this kind of source. For example, Norquest College provides guidelines for citing Indigenous Elders and Knowledge Keepers⁠ —an author category that does not appear in the MLA Handbook . In cases like this, however, it's a good idea to ask your instructor or supervisor whether using third-party citation guidelines might present problems.

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 to avoid plagiarism .

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.

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 centered). 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).

When no individual author name is listed, but the source can clearly be attributed to a specific organization—e.g., a press release by a charity, a report by an agency, or a page from a company’s website—use the organization’s name as the author in the reference entry and APA in-text citations .

When no author at all can be determined—e.g. a collaboratively edited wiki or an online article published anonymously—use the title in place of the author. In the in-text citation, put the title in quotation marks if it appears in plain text in the reference list, and in italics if it appears in italics in the reference list. Shorten it if necessary.

When you quote or paraphrase a specific passage from a source, you need to indicate the location of the passage in your APA in-text citation . If there are no page numbers (e.g. when citing a website ) but the text is long, you can instead use section headings, paragraph numbers, or a combination of the two:

(Caulfield, 2019, Linking section, para. 1).

Section headings can be shortened if necessary. Kindle location numbers should not be used in ebook citations , as they are unreliable.

If you are referring to the source as a whole, it’s not necessary to include a page number or other marker.

The abbreviation “ et al. ” (meaning “and others”) is used to shorten APA in-text citations with three or more authors . Here’s how it works:

Only include the first author’s last name, followed by “et al.”, a comma and the year of publication, for example (Taylor et al., 2018).

APA Style usually does not require an access date. You never need to include one when citing journal articles , e-books , or other stable online sources.

However, if you are citing a website or online article that’s designed to change over time, it’s a good idea to include an access date. In this case, write it in the following format at the end of the reference: Retrieved October 19, 2020, from https://www.uva.nl/en/about-the-uva/about-the-university/about-the-university.html
