• Leonardo da Vinci → da Vinci, L.
• George W. Ogden → Ogden, G. W.

• Sir Arthur Conan Doyle → Doyle, A. C.
• Dr. Martin Luther King, Jr. → King, M. L., Jr.

Some authors use non-standard capitalization. Retain that capitalization.

• danah boyd → boyd, d.

Some names, such as those with religious or nobility titles, may need to be listed differently in the References page in order to preserve the meaning.

• Pope Francis
• Queen Raina
• Plato

List authors in the order they appear on the source. A comma should separate each author's name, and an ampersand (&) should precede the last author's name. Spell out up to twenty authors' names in the reference list in this format:

Two Authors:

Three to Twenty Authors:

21+ Authors:

Some resources may be attributed to a group or organization, instead of a specific person or persons. In this case, give the name of the group or organization, capitalized as needed. You may abbreviate the organization to a common abbreviation beginning with the second in-text citation.

Book Editors

If a book is compiled by an editor (usually specified on the cover or title page), list the names as usual, but add (Ed.) or (Eds.) after the names, to signify editor or editors. This abbreviation is not included in the in-text citation.

Audiovisual "Authors"

Audiovisual materials may have different people for the author element. Common examples include director, host, executive producer, musical artist, composer, or a producer. Include a parenthetical clarification of the role.

If there is no listed author or editor, start your reference with the title, place the date after the title, and continue the reference as normal. Remember that authors can be a company, organization, or group author, and that should be used as the author if provided. Check very carefully to ensure that there is no organization that can be used as the author!

Template

Title. (Date). Source.

Examples

Oxford English dictionary (2nd ed.). (1989). Clarendon Press.

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

For in-text citations, use the title of the item, followed by the date. If the title is long, you may abbreviate it to the first few words. Book titles are italicized; journal or website articles are put in quotations.

(Oxford English Dictionary, 1989).

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

If the item is expressly attributed to "Anonymous," list that as the author:

Anonymous. (2006). Go ask Alice. Simon Pulse.

(Anonymous, 2006)

Most sources (such as books, journal articles, and films) only require the year. For magazines, newsletters, newspapers, social media, YouTube videos, blog posts, etc., provide the full date.

Valinsky, J. (2019, October 8). Instagram dark mode is here. CNN. https://www.cnn.com/2019/10/08/tech/instagram-dark-mode-trnd/index.html

In-text citations, however, will only include the year.

(Valinksy, 2019)

If an item does not have a discernible date, you may use n.d. as the date (for no date); do not simply leave out the date. For webpages, do not use a general copyright date given for the website. Look for a specific created, updated, or modified date for the page or document you are using.

Santa Fe College. (n.d.). Fifty years to first. https://www.sfcollege.edu/about/50/

(Santa Fe College, n.d.)

If you have two or more distinct works by the same author and published in the same year, differentiate them with letters. Organize these references by the title element.

Rowling, J. K. (1999a). Harry Potter and the chamber of secrets. Arthur A. Levine.

(Rowling, 1999a)

Rowling, J. K. (1999b). Harry Potter and the prisoner of Azkaban. Arthur A. Levine.

(Rowling, 1999b)

For items that have a full date, such as blogs or newspaper articles, add the differentiating letter to the year, and keep the month and/or day. Recall that only years are included in an in-text citation. Organize them in the references list by date.

Flaherty, C. (2018a, March 14). Same course, different ratings. Inside Higher Ed. https://www.insidehighered.com/news/2018/03/14/study-says-students-rate-men-more-highly-women-even-when-theyre-teaching-identical

(Flaherty, 2018b)

If both items are using n.d. instead of a year, include a hyphen before the differentiating letter. Organize these references by the title element.

Santa Fe College. (n.d.-a). Honors student code of conduct. https://www.sfcollege.edu/honors/honors-student-code-of-conduct/index

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

If you are citing a classic work that has been reprinted or republished, you can include the original date at the end of the reference. Include both dates in the in-text citation.

Freud, S. (2005). Civilization and its discontents. Norton. (Original work published 1930)

(Freud, 1930/2005)

If the resources you are citing may change substantially before readers can access it, you may add a retrieval date prior to the URL. Examples include wikis, dictionary entries, Twitter profiles, webpages that update frequently, etc.

APA requires you to only capitalize certain words in a title. You should capitalize the following:

• The first word of the title
• The first word of the subtitle, usually directly after a colon :
• Any proper nouns (places, people, organizations, etc.)
• All significant words in a journal/website title

Examples of Correct Capitalization:

• Aces high: The heroic saga of the two top-scoring American aces of World War II
• Can’t remember what I forgot: The good news from the front lines of memory research
• The elements of library research: What every student needs to know
• The FBI: A history
• Introduction to research in the health sciences
• Journal of Studies on Alcohol and Drugs [journal title]
• The Oxford guide to library research
• Preparing research articles
• Publication manual of the American Psychological Association

APA requires you to italicize the titles of stand-alone works:

• books
• journals
• films
• reports
• webpages

If you are citing something that is part of a bigger work, you do not italicize the titles:

• chapters in books
• title of entry in a reference book
• articles from journals, magazines, or newspapers

If a title ends with a non-period punctuation mark (such as a question mark or an exclamation mark), use that as the ending punctuation without adding a period.

Jacobs, J. B. (2002). Can gun control work? Oxford University Press.

(Jacobs, 2002)

If the title uses an em dash instead of colons for a subtitle distinction, preserve those.

Format Clarification

If the information you are citing is not a routine format, use square brackets after the title to clarify. Common examples include:

• [Video]
• [Tweet]
• [App]
• [Painting]

In very rare cases, you may be using a source without a specific title. This may be something like a social media post, untitled artwork, or a Google map. In the title component, include a description in brackets; try to include the medium in the description if possible.

Database Information

Only include the name of a library database you used to retrieve information if the source you are using is exclusive to that database. Most journals, magazines, and newspapers would not fit this criteria. Some databases such as the Cochrane Library or Opposing Viewpoints database will fit into this category.
