How to Cite a Website and Online/Electronic Resources

The pages outlines examples of how to cite websites and media sources using the Harvard Referencing method .

What are electronic sources?

An electronic source is any information source in digital format. The library subscribes to many electronic information resources in order to provide access for students. Electronic sources can include: full-text journals, newspapers, company information, e-books, dictionaries, encyclopaedias, economic data, digital images, industry profiles, market research, etc. 

Should I include extra information when I cite electronic sources?

Referencing electronic or online sources can be confusing—it's difficult to know which information to include or where to find it. As a rule, provide as much information as possible concerning authorship, location and availability.

Electronic or online sources require much of the same information as print sources (author, year of publication, title, publisher). However, in some cases extra information may be required:

• the page, paragraph or section number—what you cite will depend on the information available as many electronic or online sources don’t have pages.
• identify the format of the source accessed, for example, E-book, podcast etc.
• provide an accurate access date for online sources, that is, identify when a source was viewed or downloaded.
• provide the location of an online source, for example, a database or web address.

In-text citations

Cite the name of the author/ organisation responsible for the site and the date created or last revised (use the most recent date):

(Department of Social Services 2020)

According to the Department of Social Services (2020) ...

List of References

Include information in the following order:

• author (the person or organisation responsible for the site
• year (date created or revised)
• site name (in italics)
• name of sponsor of site (if available) 
• accessed day month year (the date you viewed the site)
• URL or Internet address (between pointed brackets). If possible, ensure that the URL is included without a line-break.

Department of Social Services 2020, Department of social services website , Australian government, accessed 20 February 2020, <https: //www .dss.gov.au/>.

Specific pages or documents within a website

• author (the person or organisation responsible for the site)
• year (date created or last updated)
• page title (in italics)
• name of sponsor of site (if available)
• accessed day month year (the day you viewed the site)

Go back a generation and you’ll find that websites were rarely used as a source for academic essays and papers. Crazy to think about, right? Instead, students relied almost entirely on good old-fashioned paper sources such as textbooks, books and journals.

Of course, now it’s difficult to imagine life without the Internet. And the rise of the smartphone means that we all literally have a world wide web of information at our fingertips, 24/7! This easy-to-access information is super useful for school and life. However, just as with traditional sources, any website you use while researching and writing must be properly referenced. Failure to do this is plagiarism, which, whether accidental or not, can carry strict consequences.

The good news is there’s clear guidance on how you should reference your website sources, depending on which style of citation you’re required to use. APA, MLA and Chicago are three common styles. If you’re unsure which one you should be using, ask your instructor for their preference.

What Information Do I Need?

When researching online, it’s essential that you note the websites you are using as you go—not after when you might forget. It can be very easy to disappear down the Internet rabbit hole and lose track of what information came from where! You could also bookmark important web pages to give yourself an easy online record of your digital sources.

Important note: the Internet contains a wide variety of different types of material that you may need to reference, from articles and blog posts to images and videos. Correctly citing a website will depend on the type of source that you wish to cite. For illustration purposes we’ve used the following article on a website:

• Author/s name: Janna Anderson and Lee Rainie
• Article title: The Future of Well-Being in a Tech-Saturated World
• Website title: Pew Research Center: Internet & Technology
• Publication date: 17 April 2018
• Access date: 9 May 2018
• Website publisher: Pew Research Center
• URL: http://www.pewinternet.org/2018/04/17/the-future-of-well-being-in-a-tech-saturated-world/

In-Text Citations

In-text citations may also be included in the body of your work to help the reader identify the section that relates to the full citation on your works cited page. These are also known as parenthetical citations, as they’re often enclosed (like this), and MLA refers to them as citations in prose. The format of your in-text citations will vary depending on the citation style you are using.

Let’s take a look at some examples of how to cite a website in MLA, APA and Chicago styles.

How to Cite a Website in APA Style

APA in text citation : (Anderson & Rainie, 2018)

Full citation:

Anderson, J., & Rainie, L. (2018). The future of well-being in a tech-saturated world. Retrieved from http://www.pewinternet.org/2018/04/17/the-future-of-well-being-in-a-tech-saturated-world/ .

How to Cite a Website in MLA Style

How to Cite a Book in Chicago Style Format (footnote/bibliography style)

Janna Anderson and Lee Rainie, “The Future of Well-Being in a Tech-Saturated World,” Pew Internet , April 17, 2018, accessed May 9, 2018, http://www.pewinternet.org/2018/04/17/the-future-of-well-being-in-a-tech-saturated-world/.

Bibliography:

How to cite a website in a bibliography using MLA

The most basic entry for a website consists of the author name(s), webpage title, website title, *sponsoring institution/publisher, publication date, and DOI or URL.

Author Last Name, First Name. “Webpage Title.” Website Title , *Sponsoring Institution/Publisher, Publication Date, DOI or URL.

Owoseje, Toyin. “Britney Spears Apologizes to Fans for ‘Pretending’ to be OK in her Conservatorship.” CNN , 25 June 2021, cnn.com/2021/06/25/entertainment/britney-spears-conservatorship-instagram-intl-scli/index.html.

*If the sponsoring institution or publisher’s name is the same as the website title, do not include it. MLA prefers to avoid duplicating information in citations.

The first author’s name should be reversed, with a comma after the last name, followed by a period after the first name (or any middle name). The name should not be abbreviated and should be written exactly as it appears on the website. Titles and affiliations associated with the author should generally be omitted. A suffix, such as a roman numeral or Jr./Sr. should appear after the author’s given name, preceded by a comma.

For a page with two or more authors, list them in the order they appear on the website. Only the first author’s name should be reversed, while the others are written in normal order. Separate author names by a comma, and place the word “and” before the last author’s name.

Sanchez, Ray, and Eric Levenson. “Derek Chauvin Sentenced to 22.5 Years in Death of George Floyd.” CNN , 25 June 2021, cnn.com/2021/06/25/us/derek-chauvin-sentencing-george-floyd/index.html.

For pages with three or more authors, reverse the first author’s name as described above and follow it with a comma and the abbreviation “et al.” Do not italicize “et al.” in parenthetical citations or works-cited list entries.

Rebaza, Claudia, et al. “John McAfee Was Not Suicidal, Says Widow of Antivirus Software Magnate.” CNN , 25 June 2021, cnn.com/2021/06/25/tech/john-mcafee-wife-janice-intl/index.html.

If the article was written by a news service or organization, include the name in the author position and remove any introductory articles (e.g.,  A, An, The) from the name.

Associated Press. “Obama Inaugurated as President.” CNN , 21 Jan. 2009, cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html.

If no author is available, begin the citation with the webpage title.

“Obama Inaugurated as President.” CNN , 21 Jan. 2009, cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html.

The webpage title should be placed within quotation marks. Place a period after the webpage title within the quotation marks. The webpage title is followed by the name of the larger website container in italics, and it’s usually followed by a comma and any additional information such as version, number, publisher, publication date, or URL. The punctuation before the version element varies depending on whether the webpage is part of a larger work or “container.” When it is part of a larger work, use a comma followed by the version. When it is a work that stands alone, use a period followed by the version.

Smith, John. “Obama Inaugurated as President.” CNN , Version 12.1.1., 21 Jan. 2009, cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html.

Include the sponsoring institution or publisher with a comma after the website title (or version number, if available). The sponsoring institution/publisher can usually be found at the bottom of the website in the footer. You may omit the publisher’s name when there is no publisher or when the publisher name isn’t required (for example, when the publisher title matches the website title or the website doesn’t list the publisher responsible for producing the work).

Smith, John. “Obama Inaugurated as President.” CNN , 21 Jan. 2009, cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html.

Next, state the publication date of the webpage.  In works-cited list entries, use only the day-month-year style. Month names should be abbreviated, except for May, June, and July, and followed by a period. In some cases, a specific date might not be available, and the date published may only be specific to a month or even year. Provide whatever date information is available. When using seasons in the date, lowercase the season (spring 2021 not Spring 2021). If there is no date available, you may omit the publication date element from your citation. However, you may wish to include an access date in the supplemental element slot after the URL.

Smith, John. “Obama Inaugurated as President.” CNN , cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html.

Smith, John. “Obama Inaugurated as President.” CNN , cnn.com/2009/01/21/politics/obama-inaugurated-as-president/index.html. Accessed 21 Jan. 2021.

According to MLA’s 9th edition, updated in 2021, you may usually leave out http:// or https:// from URLs unless you want to hyperlink them or unless instructed otherwise. When in doubt, ask your instructor. If a DOI is available, use that instead of the URL. For DOIs, use http:// or https:// before the DOI: https://doi.org/xx.xxxx/xxx.xxxx.xxxx. Use a period after the DOI and the URL.

Smith, John. “Obama Inaugurated as President.” CNN , 21 Jan. 2009, https://doi.org/12.3456/789.1011.1213.

For an online news source with more than two authors (3+), use “ et al ” after the first author to indicate “ and others ” in your works cited entry. With this format, you do not have to write all the authors’ names since you are indicating the same using “et al.”

Last Name, First Name1, et al. “Title of the article.” Title of the newspaper , Date of publication, URL.

Kamelion, North, et al. “How do Zebras stay awake in the forest amidst a scavenger hunt?” Taj Road Journal , 9 Aug. 2020, www.tajroadjournal.com/posts/253839.

If you have the same author as the first author in more than one entry, then distinguish these entries by listing two authors in the entries and using “et al” for the other authors.

If there is no author given for an online news source, then the in-text citation should include the first main word or words of the article title within the quotation marks. For example:

In a works-cited entry, you will include the article title, newspaper name, publication date, and URL. See below for the format and example.

“Article Title.” Newspaper , Date, URL.

“High Winds Blow Michigan Anglers, Ice Shanty about a Mile across Saginaw Bay.” Detroit Free Press , 2022 March 7, https://www.freep.com/story/news/local/michigan/2022/03/07/saginaw-bay-ice-shanty-winds/9411709002/.

How to Add a Website to a Bibliography

Last Updated: December 19, 2022 Fact Checked

This article was co-authored by Diane Stubbs and by wikiHow staff writer, Jennifer Mueller, JD . Diane Stubbs is a Secondary English Teacher with over 22 years of experience teaching all high school grade levels and AP courses. She specializes in secondary education, classroom management, and educational technology. Diane earned a Bachelor of Arts in English from the University of Delaware and a Master of Education from Wesley College. 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 163,360 times.

As much information as is available on the internet, you may want to use a website as a source for a research paper. When you do, you have to include an entry in your list of references at the end of your paper. Most of the information contained in that entry will be the same regardless of what citation style you use. However, the format varies depending on whether you're writing a Works Cited entry in Modern Language Association (MLA) style, a Reference List entry in American Psychological Association (APA) style, or a Bibliography entry in Chicago style.

• In-Text Citations

Author, A. A. (Year). Title of page . Website. http://xxxxx

General copyright dates are not sufficient to use as the publication date. If no creation or publication date is given, use n.d. If the author and website are the same, omit the website.

Example 1: Author, No Date

Corcodilos, N. (n.d.). Keep your salary under wraps . Ask the Headhunter. http://www.asktheheadhunter.com/hasalary.htm

(Corcodilos, n.d.)

Example 2: Corporate Author

Example 3: Multiple Pages from One Website

If you are using multiple pages from one website that all have the same author and date, differentiate the dates with letters. Be sure that the citations are listed alphabetically by webpage title.

Centers for Disease Control and Prevention. (2014a). Be safe after a hurricane . http://emergency.cdc.gov/disasters/hurricanes/be-safe-after.asp

(Centers for Disease Control and Prevention, 2014a)

Centers for Disease Control and Prevention. (2014b). Make a plan . http://emergency.cdc.gov/disasters/hurricanes/plan.asp

(Centers for Disease Control and Prevention, 2014b)

If both items have n.d. instead of a year, include a hyphen before the differentiating letter:

Santa Fe College. (n.d.-a). Priority admissions dates . http://www.sfcollege.edu/admissions/index.php?section=priority_dates

(Santa Fe College, n.d.-a)

Santa Fe College. (n.d.-b). SF to UF: A true story . http://www.sfcollege.edu/gators/true-story/index

(Santa Fe College, n.d.-b)

Example 4: No Author

Appeal to authority . (n.d.). Logical Fallacies. https://www.logicalfallacies.org/appeal-to-authority.html

When citing as an in-text citation, you may abbreviate the title to the first few words, in quotations, unless the title is short:

("Appeal to Authority," n.d.)

How to Cite Internet Sources

Print sources posted online, online versions of print periodicals, databases (like lexis-nexis), online journals, organization websites, topic websites, private websites, online video (like youtube), forums, listservs, chats, & bulletin boards, email & instant messages, i nternet vs. print sources.

Some professors will discourage you from using sources you find or access over the Internet. Although such restrictions may be excessive, there are reasons to be wary. It’s much easier to publish information on the Internet than to publish a book or periodical in print. Since it’s easier, Web posters are not always as careful to make sure that the information is accurate. For one thing, print publishing is more expensive, so many print publishers are careful not to make mistakes or to cut corners, in case what they publish turns out to be unreliable—and therefore useless. The seeming anonymity of the Internet also encourages some people to write things quickly, without checking to be sure of their facts or their conclusions. Most of us have had the experience of sending by email something we wrote quickly—perhaps when rushed or angry. Often these are things we wouldn’t print, sign, and mail, because those extra steps give us time to consider our words more carefully, and also because we recognize a higher expectation that things in print should be trustworthy.

N o Author, No Authority

In the context of writing in college, material from much of the Internet is less reliable than print sources because it’s hard to tell who wrote or posted it. As discussed in the section  Why Cite? , the essence of academic scholarship is a conversation among authors. On many websites, it’s difficult to determine the author of the material. If the site creator’s name is listed, it’s still sometimes hard to tell whether the information has been reprinted from some other source. If you reach a website through a search engine, you may have to find the site’s homepage or search around in the “contact” information in order to identify the author or the organization that sponsors the site. Even if you find the author’s name, Internet sources make it harder to tell what status that person has in his or her field. Is the author an expert, a fan, or just a crackpot? After finding a website that seems useful and tracking down the author’s name, you may need additional research (perhaps using Google) to learn whether the author has any claim to credibility.

But of course, countless reliable sources can be accessed on the web, and even unreliable sources have some uses in research writing. (See  Scholarly vs. Popular Sources  for more about unreliable sources.) These days, many students and scholars use Web sources extensively in research and teaching. But they take extra care to assess and report the provenance of these sources.

Types of Websites

In this guide’s discussion of Internet sources, we draw distinctions between various kinds of websites: those sponsored by  organizations , those devoted to a  single topic , and  private websites  that are maintained by a single person—often a devoted fan of the topic under discussion. To some degree, these categories distinguish more and less reliable sources of information. But the distinctions are neither clear nor entirely stable. Some organizations, while established leaders in their fields, have very few resources available to maintain and update their websites. Some private individuals, although hosting websites as a hobby, are experts in their fields and consider accuracy on their sites to be the highest priority. It’s often useful to identify your source in the body of your paper (and not just in your citation or footnote); this identification is especially important when you use material from the Internet. If you give a sense of what kind of Web source you’re using, the reader will be better able to understand the context of your evidence.

Basics of Citing Websites

When listing Internet sources in your References or Works Cited, the most important thing to remember is that your goal is to make it easy for a reader to consult your sources. (This same goal is paramount when listing print sources.) For most sites, that means you should include the  full  URL for the page you cite in your paper (the web address that begins “http”). But websites change, and the address you used won’t always be active when your reader tries to view a source. For that reason, it’s important to include both the date you accessed the site and also a full account of the person, group, or organization that sponsors the site. Knowing more about the author helps readers to assess the source and also, sometimes, to find the source when the website has been moved or revised.

The general form of a citation from an Internet source is:

Author’s name. Title of Document. Title of Website. Sponsor of Website. Date of Document. Date of Access. URL.

As you will see in the discussion of specific categories, however, some of these items may be hard to determine.

Avoiding Plagiarism

The ease of using electronic sources of any kind can make it harder to keep track of where the source ends and your original contribution begins—and you must always keep that distinction clear. See  How to Copy and Paste but Not Plagiarize  for advice about how to use electronic sources wisely.

Respecting Privacy

Most of this guide focuses on helping you subordinate sources to your own ideas. In general, we highlight your need to respect authors’  intellectual  or  property  rights, explaining how to give people credit for their ideas while distinguishing your own original contributions. But the ease of using electronic sources also raises dangers about what might be called  privacy  rights, leading you to make public words that the original author intended only as private communication. When someone speaks in public, participates in an interview, or publishes a piece of writing, he or she implicitly agrees that other people may refer to this material in research. But some electronic sources blur the line between public and private communication. (Private communications also have a different force of authority than deliberately published material; see  Scholarly vs. Popular Sources  for more information.)

If in doubt about whether a given text should be considered public or private, we urge you to check with the original author before quoting it in your own work. Although the following categories overlap, they may help you decide when more care is warranted to avoid an invasion of privacy. (1) Web versions of sources that also appear in print are generally safe to quote, since most print publishers take care to secure rights before publication. (2) Publicly accessible websites are generally safe to quote. You may occasionally find a website reposting information that’s clearly from category 3, in which case you may wish to contact the original author before using the material. But if you can access the information through regular surfing, without passwords, it’s probably safe to use. (3) Communications sent via email or accessed by membership in a specific group are generally considered private, and you should exercise care in quoting from them in your papers.

Even in this last category, there’s not a hard and fast rule you can follow. If your university sends an announcement to all students via email, you may reasonably consider this public information. If your best friend reveals something damaging or embarrassing in an email sent only to you, it’s clearly private. But what if a professor writes to you about something related to the course? Or if you receive a message that’s sent only to the members of a small club? What about the discussion forums that many courses set up for students to exchange ideas about the readings? These cases are all ambiguous. Unless there’s been an explicit agreement that the material is public, we encourage you to check before using such messages in your work.

Copying Text Without Plagiarizing

One convenience of using electronic sources is the ability—once you’ve selected the passages you wish to quote—to copy and paste quotations instead of having the retype them into your paper. Even before you begin drafting a paper, copying and pasting sections from your sources seems an easy way to take notes, so that you can look the material over later without surfing back to the website. This very convenience, however, also leads writers into danger. In the midst of researching and taking notes, it’s just too easy to paste quotations into your file with the intention to go back later and note down the source. When you return to your draft, it can be hard to distinguish your own writing from the passages you’ve copied.

As discussed in  Understanding and Avoiding Plagiarism , the worst consequence of failing to acknowledge sources is to yourself: if you paste in someone’s words as your own, you will miss the opportunity to add your commentary, and therefore miss an opportunity to grow as a thinker and writer. Most of this guide focuses on such intellectual reasons for working properly with sources, rather than emphasizing the penalties of plagiarism. But because the copy and paste technique is so common, it’s especially important to warn you about its potential for abuse. Every year students come before the Yale Executive Committee having committed plagiarism through pasting material from the Internet into their papers and then forgetting to go back and identify the sources. Even when the oversight seems unintentional, these students are guilty of plagiarism, and must face penalties.

But you can avoid this danger with one very simple precaution:

Every time you highlight material from a website to use in your paper, save the material to a new file. Copy the URL (the full web address that begins with “http”) at the top of the new file, and give the file a name that briefly identifies the website.

Taking this extra step will allow you to review your sources when you’ve made more progress with your paper. So if you were thinking of using a piece of this web page in your paper, you’d copy the relevant portion into a Word file, add the URL, and perhaps call the file “Writing at Yale Copy/Paste Advice.” You’ll still be able to avoid retyping by copying and pasting from the new file you’ve made. But you will have created a record of your excerpts to help you distinguish your sources from your own work. For your own convenience, you may also want to add other citation information below the URL—such as author and date of access—before moving on to examine the next website. See  Special Demands of Internet Sources  for more information about how to cite websites. See also  Scholarly vs. Popular Sources  for advice about how to use Internet sources effectively.

Note: Even when you properly identify Internet sources, the very pasting that feels like a time-saver can lead you to use block quotations that are longer and less precise than necessary. Many writers, especially beginning academic writers, are better served by retyping quotations, because this extra step leads them to edit quotations and to paraphrase. You could still cut and paste to help you keep track of interesting passages before deciding which ones to quote in your paper (remembering, as suggested above, to create a new file for each website you work with).

If a print journal, magazine, or newspaper maintains a version of its publication URL online, articles that you cite are listed in your Works Cited or list of References by the name of the article’s author. In MLA style, the name is followed by the title of the article—in APA, the publication date comes after the author. (If no author is identified, list by the article’s title. In that case, be sure to give at least a few key words from the title in the body of your paper, so that readers know how to find the source in your bibliography.) Next list the title of the journal, magazine, or newspaper. Give the publication date of the article next for MLA, followed by the date that you accessed the site. For APA , give the full URL—the Web address that begins with “http.” When a DOI (Digital Object Identifier) is available, list the DOI instead of the URL. (A DOI is a unique alphanumeric string assigned by a registration agency to identify content and provide a persistent link to its location on the Internet.)

Note: If you use a database service (such as Lexis-Nexis) to access electronic sources, you must credit the database. See  Databases (like Lexis-Nexis)  for more information.

Also note: Although online versions of print sources are often more reliable than online journals or private websites, their reliability is no greater than that of their print versions. See  Scholarly vs. Popular Sources  for more information.

Also note: In the Bibliography, Chicago style adds the URL (the Web address that begins with “http”), and does not name the database service directly if that name is part of the Web address. For Chicago, as for APA„ when a DOI (Digital Object Identifier) is available, list the DOI instead of the URL. (A DOI is a unique alphanumeric string assigned by a registration agency to identify content and provide a persistent link to its location on the Internet.)

Several companies maintain databases that make it easier to find articles on the topic you’re researching. Using these databases is especially helpful for connecting you to scholarly sources, which have been vetted by experts in their field before publication. The Yale library system subscribes to many such databases, allowing you to access them for free. See  Scholarly vs. Popular Sources  for more information about using scholarly sources. If you use a service like this—such as Lexis-Nexis—to find an article that you then cite in your paper, you must include the database name in your Works Cited or list of References. (The principle is that you want your reader to know how to retrieve your source for further research.)

Note: You may notice that listing Internet sources often takes more time and care than listing print sources. Since the authorship and location of Web sources are harder to establish, readers need even more information in order to assess sources and to retrieve them for further study.

An online journal is a website that publishes new material on a regular schedule (often weekly or monthly), with a journal title or other masthead, but that does not release a print publication. An online journal is not the same as the online version of a periodical that also publishes in print. (See  Online Versions of Print Periodicals .) The distinction matters, because online journals—while often more reliable than  private websites —are often considered less reliable than print sources or Internet versions of print sources. See  Scholarly vs. Popular Sources  for more information.

When including an article from an online journal in your Works Cited or list of References, list it by the name of the article’s author. This information is followed in MLA style by the article’s title, by the publication date in APA style. (If no author is identified, list by the article’s title.) Next list the online journal’s name. Give the publication date of the article (for MLA), followed by the date that you accessed the site. Finally, give the full URL—the Web address that begins with “http.” When a DOI (Digital Object Identifier) is available, list the DOI instead of the URL. (A DOI is a unique alphanumeric string assigned by a registration agency to identify content and provide a persistent link to its location on the Internet.)

Many organizations maintain websites hosting information about the organization or about the field that they work in. Some examples include commercial companies, universities, non-profit organizations, political groups, and government agencies. The reliability of these websites varies widely, as these organizations often use their websites to promote specific causes and may therefore emphasize only the facts and ideas that support their goals. See  Scholarly vs. Popular Sources  for more information.

But sometimes these organizations have the most comprehensive coverage of topics that pertain to them. For certain topics, it’s also useful to examine what the interested parties say, even if you must remember to balance it with research into other points of view. If you are conscientious about identifying who sponsors the site, your reader will be better prepared to examine the material you present. Websites hosted by university departments and programs would generally be considered reliable sources, especially in their areas of scholarly expertise. (More caution is warranted when the site discusses politics or issues of university governance. Be careful, too, to distinguish sites created by individual faculty members from those sponsored by the larger institution.)

Whenever possible, you should identify the author of the material you use from a website. Some pages you access will have separate titles or sub-titles, which can be used like the titles of an  article in a journal . This title is followed by the name of the main website, if there is one, and the name of the sponsoring organization. After this comes the full URL for the material you’re using.The final item is the date that you accessed the site.

Note: It’s sometimes hard to find the author of material on an organization website. In that case, list by the title of the site—if there is one—or by the name of the organization. If you can’t find any of this information, even after searching through the site’s links, you may be using a  private website  or  topic website , and should review the information for those sources.

Websites that are  print sources posted online ,  online versions of print periodicals ,  online journals , or  organization websites  are discussed separately. By “topic websites,” we mean sites that are dedicated to a single issue, such as the life of a famous person, the main ideas of a social movement, or the details of a popular television show. This category is a little hard to define. Unlike online journals or other periodicals, topic websites are not usually revised on a regular schedule, although material may be added from time to time. And unlike organization websites, topic websites do not usually promote the products or mission of a particular institution—which means they also don’t have the organization’s reputation to back up their authority. Finally, topic websites may also overlap with private websites, which often focus on a single issue that their author is passionate about.

Still, the category is worth knowing about, because a lot of background information on general topics like “Medieval Literature” or “Film Noir” is found on websites that don’t easily fit any of the other categories. You’ll want to double-check material you find on Topic Websites, and you may need to treat them as  popular sources  rather than  scholarly sources . If you take these precautions, topic websites are sometimes useful for giving a broad overview or putting you on the track of more authoritative sources. (See  Special Demands of Internet Sources  for more information.)

When these websites appear to be wholly or primarily the work of one author, list by the author’s name, followed by the title of the article or specific page you’re using (if there is one), the website title (often the name of the topic), the date of posting (if known), the date you accessed it, and the full URL—the Web address that begins with “http.”

If the site you’re using is sponsored by an organization of some kind (like a company, a university department, or a political group), it may qualify as an  organization website , and you should review the information for those sources.

Private websites come in many forms. Some dabble in multiple topics, about which the site’s author may not even profess any special expertise. Some announce themselves as fan sites, indicating that the author has an intense interest but no special background or credentials. Still others are quite professional in presentation, with authors who profess or demonstrate vast experience.

Just a few years ago, unreliable websites were often riddled with typographical errors or burdened with amateurish design and graphics. But it’s increasingly easy to host websites that look polished and professional, which can make it hard to judge whether the site’s sponsors take seriously the responsibility to check and update their information. For the purpose of academic research, most private websites should be considered popular sources, which can be useful as sources of opinion but should generally not be relied on for authoritative information. (See  Popular vs. Scholarly Sources  for more information.)

It’s often useful to identify your source in the body of your paper (and not just in your citation or footnote); this identification is especially important when you use private websites. If you give a sense of what kind of web source you’re using, the reader will be better able to understand the context of your evidence. Private websites also raise issues of privacy, as some sites that require password access may not invite republication of their material in scholarly research. See  Special Demands of Internet Sources  for more information.

When using material from a private website, list by the author (if known), then by the title of the article or specific Webpage you’re using (if known), and the date of posting (if listed). Follow this by the title of the website, if applicable. If the site is part of an identifiable online group (like “Facebook” or “tumblr”), include that title next. Next, list the date that you accessed the site and the full URL—the Web address that begins with “http.”

Some of these details may be hard to identify. In the example above, for instance, it was not possible to determine when the specific section of the website was last updated. Only the date of access is given.

Blogs—an abbreviation of “weblogs”—are websites or areas of websites devoted to dated reflections by the site’s author. Many blogs are hosted on or presented as private websites where the author claims little special expertise or no professional affiliation relevant to the blog’s topic. In these cases, see the discussion of  Private Websites , and use the same care when evaluating the material you access.

But blogs are increasingly included as a feature of  organization websites  (Amazon.com, for instance, now invites authors to post blogs on their work) or as elements of  online versions of print periodicals  (the  New York Times  website hosts several blogs by reporters and editors). When using a blog that’s identified with a larger journal or organization, follow the advice listed for those general sources.

Even when hosted by a recognized organization, most blogs should probably be treated as popular rather than scholarly sources. See  Scholarly vs. Popular Sources  for more information.

The example above also lists “Livejournal” as the site’s sponsor. This information might be considered analogous to the organization that sponsors an  organization website . But in some cases, it may not be necessary to give the site sponsor. Livejournal, for instance, does not supervise posters’ comments very closely. A sponsor like “Facebook” has more rules and some restrictions to access, but is still doesn’t stand behind the material as much as an  online journal  would. When deciding whether to include the site sponsor, use your judgment: if the blog pursues a theme in common with the sponsor, list the sponsor.

Note: It’s often useful to identify your source in the body of your paper (and not just in your citation or footnote); this identification is especially important when you use blogs. If you give a sense of what kind of web source you’re using, the reader will be better able to understand the context of your evidence. See  Special Demands of Internet Sources  for more information.

The formats below cover the most common ways to cite video clips that were published online (on sites like YouTube and Vimeo). Video that was first published elsewhere but accessed online (on sites like Netflix and Hulu) is cited differently. See the notes that follow for more information.

MLA: TED. “Philip Zimbardo: The Psychology of Evil.” Online video clip.  YouTube . YouTube, 23 Sept. 2008. Web. 8 Aug 2015. < https://www.youtube.com/watch?v=OsFEV35tWsg>  [author’s name or screen name.] [“title of video.”] [media type.] [ name of website .] [site sponsor or publisher,] [posting date.] [medium.] [date of access.] [.]

Note: If you know both the author’s name and his or her screen name (and they are different from one another), APA style cites the author’s name first (last name, first initial) followed by the screen name in square brackets (e.g. Booker, J [jbook].).

Chicago: 24. TED, “Philip Zimbardo.” [fn. #.] [author name or screen name, “shortened title.”] [Shortened Chicago reference; see  More Notes on Chicago Style  for more information.]

Like other film and video formats, conventions for citing online video are less fixed than those for print or other kinds of online sources. The citation for a video clip that was first published online typically attributes the clip to the individual who posted it on the Internet. Video that was first published elsewhere before being posted online, is usually attributed to the individuals most responsible for making it—the director or performers. See the citation formats for Film & Video and Television, Radio Program, or Music Video for more information.   Depending on who seems most responsible for the existence of the video you’re citing, you may choose to attribute an online video to its creators rather than the individual who posted it. For example, a film that is released online or an ongoing web series, may be more accurately attributed to the director or actors than the person who uploaded it to the Internet. For citation formats that attribute video to the actors or director, see Film & Video and Television, Radio Program, or Music Video .

There are many electronic forums that allow users with a specific interest or affiliation to discuss topics with each other. Some of these are restricted to members of a group, or of a specific course. (Many Yale courses, for instance, provide forum discussions through the Classesv2 server.) Other such discussions are open to any interested party. Although discussions limited to professionals in a field may be more authoritative, in general you should probably treat material from these forums as popular rather than scholarly sources. See  Scholarly vs. Popular Sources  for more information.

Note: Many such forums expect communications to be private. Be sure to check the group’s policies on reproduction of such material. Even if an FAQ or moderator seems to make reproduction permissible, a decent respect for privacy suggests that you secure the poster’s permission before making the material public.

If you use material from an electronic forum, list by author’s name. Follow that with the most specific identifying information you can give about the particular post. Depending on the type of discussion, there may be subject headings or specific message numbers on a given post. You may or may not be able to tell the posting date.

In MLA style, include the name of the sponsoring forum. Since most of these discussions do not supervise postings, do not put the sponsor name in italics. Follow this with the date you accessed the material. Even when membership is restricted to a particular organization, most listervs should probably be treated as popular rather than scholarly sources. See  Scholarly vs. Popular Sources  for more information.

The last item in your listing—the electronic address—brings up one point on which MLA and APA styles differ starkly: in APA, if the posting cannot be retrieved, you cite it in your paper as a personal communication and do not include it in your list of References. Even in MLA style, it’s better to cite the message in the form that’s most easily accessible to your reader: many listservs archive their messages on the web, for instance, even though the original postings are delivered by email. Try to include the archive address.

Also note: As discussed in  Signaling Sources , it’s often useful to identify your source in the body of your paper (and not just in your citation or footnote); this identification is especially important when you use listservs. If you give a sense of what kind of Websource you’re using, the reader will be better able to understand the context of your evidence. See  Special Demands of Internet Sources  for more information.

MLA: Donahue, Tiane. “Re: Your WPA Question.” Message to the author. 14 Dec. 2004. Email. [author, by last name.] [“title or subject line.”] [message recipient.] [message date.] [medium.]

APA: Do not include in list of References. Cite in your paper as a personal communication.

Chicago: 25. Tiane Donahue, “Re: Your WPA Question,” email message to author, December 14, 2000. [fn. #.] [author full name, “subject heading,”] [type of message,] [date of message.]

Note: Chicago style footnotes give full information for private messages, but does not list them in the Bibliography.

It’s probably obvious that the authority of material that comes in private communications varies greatly with the status of the source. What someone writes to you by email may be useful as a source of opinion, but can seldom be relied on as definitive information, unless you’re in correspondence with a recognized expert. And even in these cases, the informality of email makes most authors much less careful about checking facts and conclusions, rendering the information less authoritative. Most email messages should probably be treated as popular rather than scholarly sources. See  Scholarly vs. Popular Sources  for more information.

Note: Most people consider email to be private. Even if the message is sent to more than one recipient, a decent respect for privacy suggests that you secure the sender’s permission before making the material public. If you received the message as a forward, the obligation to seek permission is even more urgent, as the original author likely has no reason to expect you to use the message in your own work. See  Special Demands of Internet Sources  for more information.

If you do use material from an email, the format for listing in MLA style is fairly simple, as in the example above: Author, Subject, “Email to the author,” and Date.

In APA style, you do not include in your list of References any source that can’t be retrieved by your reader. If you use email in your paper, cite it as a personal communication in your text, and do not list it at the end. For Chicago style, private messages are given full citation in a footnote, but not included in the Bibliography.

Note: As discussed in the section on  Signaling Sources , it’s often useful to identify your source in the body of your paper (and not just in your citation or footnote); this identification is especially important when you use private messages. If you give a sense of what kind of source you’re using, the reader will be better able to understand the context of your evidence. See  Special Demands of Internet Sources  for more information.

To list material from Wikipedia, you should review the advice for  organization websites . But Wikipedia merits additional attention because of its recent growth and popularity. Some professors will warn you not to use Wikipedia because they believe its information is unreliable. As a community project with no central review committee, Wikipedia certainly contains its share of incorrect information and uninformed opinion. And since it presents itself as an encyclopedia, Wikipedia can sometimes seem more trustworthy than the average website, even to writers who would be duly careful about  private websites  or  topic websites . In this sense, it should be treated as a popular rather than scholarly source. See  Popular vs. Scholarly Sources  for more information.

But the main problem with using Wikipedia as an important source in your research is not that it gets things wrong. Some of its contributors are leaders in their fields, and, besides, some print sources contain errors. The problem, instead, is that Wikipedia strives for a lower level of expertise than professors expect from Yale students. As an encyclopedia, Wikipedia is written for a common readership. But students in Yale courses are already consulting primary materials and learning from experts in the discipline. In this context, to rely on Wikipedia—even when the material is accurate—is to position your work as inexpert and immature.

If you use Wikipedia for general background, check several other sources before using the material in your essays. Some of the facts you find may be attributable to common knowledge (see  Common Knowledge  for more discussion). You may also be able to track opinions or deeper ideas back to their original sources. In many cases, your course readings will contain similar ideas in better, more quotable language. Many student writers are tempted to use Wikipedia for definitions of terms (the same way a beginning writer might quote a dictionary). But in most cases, a definition drawn or paraphrased from the primary course readings—or from other scholarly sources—will be more effective. See  Why Cite?  for more discussion of definitions and keyterms.

Of course, if you do use language or information from Wikipedia, you must cite it—to do otherwise constitutes plagiarism. The advice here is not to hide what Wikipedia contributes to your ideas, but rather to move beyond Wikipedia and write from a more knowledgeable, expert stance.

How to Write a Bibliography: Referencing Styles Explained

If you aren't familiar with writing bibliographies as part of your assignments, it can feel pretty confusing. Often, bibliographies are an afterthought or something left to the last minute. However, if you collect the information as you study, bibliographies can be a hassle-free part of your project.  

In this guide, we explain exactly what a bibliography is, the different referencing styles and where to find the necessary information.  

What is a bibliography?  

A bibliography is the list of sources you used to build your assignment. You should include anything you actively referenced in your work and anything you read as part of your project's research and learning phase, even if you don't explicitly cite them within your project.    

What are primary and secondary sources?  

Your course teacher may request you order your bibliography using primary and secondary sources. This is much more simple than it sounds.   

A primary source refers to works created by people directly connected with the topic you are writing about. For example, if you are discussing a  psychological study , a primary source would be a psychologist who was actively involved in the study.  

On the other hand, secondary sources refer to any authors that discuss the topic you are studying but have no direct association.   

What should you include in a bibliography?  

We recommend compiling your bibliography as you study. Whether or not you directly reference sources, if you use them as part of your studies, they should be included. By collecting this information and building your bibliography as you go, you’ll find it far less stressful and one less thing to worry about.    

Information required for referencing printed sources:  

• The name of the author.  
• The title of the publication or article.  
• The date of publication.  
• The page number in the book where the citation can be found.  
• The name of the publishing company.  
• If you’re referencing a magazine or printed encyclopedia, record the volume number.  

Information required for referencing web sources:  

• The name of the author or editor.  
• The title of the webpage.  
• The company that created the webpage.  
• The URL of the piece.  
• The last date you visited the webpage.  

Where to find this information  

The information you need to include in your bibliography will be located in different places, which can be pretty frustrating, particularly if you’ve left your referencing to the last minute. However, there are a few specific places where this information is likely to be found:  

• The contents page (for magazine or journal articles).  
• The first, second or editorial page (for newspapers).  
• The header or footer of the webpage.  
• The contact, or about, page of the website.  

What are the different bibliography styles?   

In addition to structuring your bibliography correctly, depending on whether your source is a book, magazine, newspaper or webpage, you need to find out what bibliographic style is required.  

  Different course tutors will ask for a specific referencing style. This means that you simply present your source information in a different order.   

There are four main styles that you might be asked to follow: MLA, APA, Harvard or MHRA, and the chosen style will change your reference order:    

MRL reference order  

• Full name of the author (last name first).  
• The title of the book.  
• Publication place.  
• The name of the book publisher.  
• The publication date.  

APA/Harvard reference order   

• If using Harvard referencing, title your bibliography as ‘References’.  
• Author’s last name.  
• Author's first initial.  
• The publication date (in brackets).  
• The book title.  
• The publication place.  

MHRA reference order   

• Author’s first and last name  
• The title of the book  
• The publication date  

Points three to five should all be included in the same bracket.

How to write a bibliography

How to write a bibiliography.

A bibliography is not just “works cited.” It is  all  the relevant material you drew upon to write the paper the reader holds.

Do I need a bibliography?

If you read any articles or books in preparing your paper, you need a bibliography or footnotes.

• If you cite the arguments of “critics” and “supporters,” even if you don’t name them or quote them directly, you are likely referring to information you read in books or articles as opposed to information you’ve gathered firsthand, like a news reporter, and so you need a bibliography.
• If you quote sources and put some of the reference information in the text, you still need a bibliography, so that readers can track down the source material for themselves.
• If you use footnotes to identify the source of your material or the authors of every quote, you DO NOT need a bibliography, UNLESS there are materials to which you do not refer directly (or if you refer to additional sections of the materials you already referenced) that also helped you reach your conclusions. In any event, your footnotes need to follow the formatting guidelines below.

These guidelines follow those of the  American Psychological Association and may be slightly different than what you’re used to, but we will stick with them for the sake of consistency.

Notice the use of punctuation. Publication titles may be either  italicized  or underlined, but not both.

Books are the bibliography format with which you’re probably most familiar. Books follow this pattern:

Author Last Name, Author First Name. (Publication Year)  Title . Publisher’s City: Publisher. Page numbers.

Alexander, Carol. (2001)  Market Models: A Guide to Financial Data Analysis.  New York, NY: John Wiley & Sons. pp. 200-220.

Periodicals

Periodicals remove the publisher city and name and add the title of the article and the volume or issue number of the periodical. Notice article titles are put in quotation marks and only the publication title is italicized or underlined.

Author Last Name, Author First Name. (Publication Date—could be more than a year) “Article Title.” Publication   Title, Vol. # . (Issue #), Page numbers.

Salman, William A. (July-August 1997) “How to Write a Great Business Plan.”  Harvard Business Review  74. pp. 98-108.

Web versions of printed material

Because web sources are time-sensitive, meaning that web content can change day by day, it is important to include the day of retrieval and the URL from which you quoted the material. You include this in a retrieval statement.

The format for online versions of print publications should basically follow the same format as above, meaning if you’re referencing an online book, you should follow the book format with the addition of the retrieval statement. If you’re referencing an online periodical, you should follow the periodical format with the addition of the retrieval statement.

Note that you should not break the Internet address of the link, even if it requires its own line. Very long URLs, such as those that occur when using an online database, can be shortened by removing the retrieval code. (The retrieval code usually consists of a long string of unintelligible letters and numbers following the end point “htm” or “html.” Remove everything that occurs after that point to shorten.)

The above is just one example of citing online sources. There are more extensive bibliographic guidelines at www.bedfordstmartins.com/online/cite6.html .

How to cite sources in the text

In-text citations alert readers to cited material and tell them exactly where to go and look. These citations work in conjunction with a bibliography.

• Usually, an in-text citation is a combination of a name (usually the author’s) and a number (either a year, a page number, or both).
• For Internet sources, use the original publication date, not your retrieval date.
• Internet sources also do not have page numbers, so use your discretion in the format that will direct the reader closest to the relevant section. You can number the paragraphs (abbreviate “par.”) or chapters (abbreviate “chap.”) or sections (abbreviate “sec.”).
• If there is no author listed, the document’s title should be used in place of the author’s name. Use the entire title but not the subtitle. Subtitles are anything appearing after a colon (:).

Use a signal phrase

A signal phrase alerts the reader to the fact that you are citing another source for the information he or she is about to read.

Myers (1997) reported that “structured decision aids, as a factor in a more structured audit approach, are designed to focus the auditor on relevant information to improve effectiveness, and to improve audit efficiency, by eliminating the time needed to develop or organize individual approaches to the audit problems.” (sec. 1, “Introduction”)

Note that the date goes with the author, directions within the document go with the quote.

Later on, same source, different section:

According to one study (Myers, 1997), inexperienced auditors from a structured firm will demonstrate higher audit effectiveness in the typical audit situation than inexperienced auditors from an unstructured firm. (sec. 2, “Structure and Audit Effectiveness”)

Full parenthetical citation after the material cited

Another method is to end the quote with the full citation:

The primary controversies surrounding the issue of accounting for stock-based compensation include whether these instruments represent an expense that should be recognized in the income statement and, if so, when they should be recognized and how they should be measured. (Martin and Duchac, 1997, Sec. 3, “Theoretical Justification for Expense Recognition”)

For long quotes, use a previewing sentence and a parenthetical citation

Long quotes are 40 words or longer and should be single-spaced even in double-spaced papers. The previewing sentence tells the reader what to look for in the quotes (and helps the reader change gears from you to another author).

Martin and Duchac (1997) reiterate the problems with stock-based compensation and accounting issues:

While it is true these estimates generate uncertainties about value and the costs to be recognized, cost recognition should be the fundamental objective and information based on estimates can be useful just as it is with defined benefit pension plans. Given the similarities between stock based compensation and defined benefit pension costs, an expense should be recognized for employee stock options just as pension costs are recognized for defined benefit pension plans. The FASB agreed with this assessment in their exposure draft on stock based compensation, noting that nonrecognition of employee stock option costs produces financial statements that are neither credible nor representationally faithful. (sec. 2.1, “Recognition of Compensation Cost”)

Note the consistent indentation and the paragraph break inside the quote. Also note that the parenthetical citation falls outside the closing period.

Source-reflective statements

Sometimes, summarizing arguments from your sources can leave the reader in doubt as to whose opinion he or she is seeing. If the language is too close to the original source’s, you can leave yourself open to charges of low-level plagiarism or “word borrowing.” Using a source-reflective statement can clarify this problem, allowing you the freedom to assert your voice and opinion without causing confusion. For example:

Myers (1997) reported that “structured decision aids, as a factor in a more structured audit approach, are designed to focus the auditor on relevant information to improve effectiveness, and to improve audit efficiency, by eliminating the time needed to develop or organize individual approaches to the audit problems.” (sec. 1, “Introduction”) Thus, audit pricing by firms with a structured audit approach is lower, on average, than firms with an intermediate or unstructured audit approach.

Is the observation in the last sentence Myers’s or the author’s? We aren’t sure. So insert a source-reflective statement to avoid confusion.

Myers (1997) reported that “structured decision aids, as a factor in a more structured audit approach, are designed to focus the auditor on relevant information to improve effectiveness, and to improve audit efficiency, by eliminating the time needed to develop or organize individual approaches to the audit problems.” (sec. 1, “Introduction”)  Myers’s observation suggests that  audit pricing by firms with a structured audit approach is lower, on average, than firms with an intermediate or unstructured audit approach.

When and how to use footnotes

You may decide to substitute footnotes for in-text citations and a bibliography. Footnotes are thorough, like entries in the bibliography, and yet specific, like in-text citations. However, depending on the thoroughness of your use of footnotes, you may also need a bibliography.

If you decide to use footnotes, you should follow the format outlined above for the information to include in your entries and should number each footnote separately (1, 2, 3, etc.). You should NOT use the same number twice, even when referencing the same document. Check out guidelines such as those in the  Chicago Manual of Style  or the  MLA Handbook  for more information about how to number your footnote entries.
