What's Unique About APA?

In-text Citations

  • Provide the last name of the author followed by a comma, then the year of publication. Example:  (Jones, 2005)
  • For works with two authors, put an ampersand between the last names of the authors. Example:  (Cook & Croft, 2015)
  • For works with three or more authors, provide the name of the first author plus "et al."  Example:  (Chen et al., 2008)
  • Include page number only in the rare case where a direct quote (placed in quotation marks) is used. Example: (Jones, 2005, p. 79)

Reference List

  • Heading: Use "References" as page heading.
  • Indentation: For each entry, all lines after the first line should be indented one-half inch from the left margin.
  • Spacing:  Double-space the entire list (both within and between entries).
  • Author: Provide the last name of the author, then the initials of the first and middle names. Put a space between the initials.  Example:  Jack, A. A.
  • Two authors:  Put a comma and an ampersand between the authors. Example:  Cook, M., & Croft, J. B.
  • Three or more authors:  Put a comma after every author.  Before the final author, put a comma and an ampersand.  Provide last names and initials of up to 20 authors.  When there are 21 or more authors, include the first 19 names, insert an ellipsis (but no ampersand), then provide the last author's name.
  • Article title: Do not place quotation marks around the article title. Capitalize only the first word of the title, the first word following a colon, and proper nouns (this form of capitalization is called "sentence case.")  Example: Interactive mindfulness technology: A walking labyrinth in an academic library
  • Journal title: Do not use sentence case; all major words should be capitalized. Example: College & Research Libraries News
  • Journal volume and issue numbers:  Italicize the volume number.  Include the issue number for all journals that have them. Place the issue number immediately after the volume number (no spaces), and enclose the issue number in parentheses. Example:  76(6)

How would I cite an indirect source?


If I read a paper by Ankeny and it cites a fact from a paper by Zeoli, and I want to refer to the fact in the paper by Zeoli, would I cite Zeoli?


No. You would cite Ankeny. Please read the "Important to know" details below, though.

How to:

Your in-text citation would look like this:

Zeoli (2002, as cited in Ankeny, 2013) argued that...

Your reference list would then include the paper by Ankeny. Your reference list would not include the paper by Zeoli, because you didn't actually read that paper.

Important to know:

In this context, Ankeny is considered an indirect or secondary source because it refers to a primary source by Zeoli. Follow the above instructions only in rare circumstances (eg, when you're not able to access the primary source). It's best to take the extra step of reading the primary source and citing it. That way, you'll know you're getting the information exactly right.  Talk with your professors about this; they might have additional advice.

Annotated Bibliographies
