APSA (American Political Science Review) Style

This brief guide provides examples of how to cite some of the most commonly used types of information resources: periodicals, books, and electronic publications.  Detailed explanations and additional types of examples are available in the following handbook located at Policy Science & Economics Library Reference.

The APSA Style Manual for Political Science, revised August 2018, is published by the American Political Science Association as a guide for authors who wish to write and submit an article for publication in one of the APSA’s journals.  It follows the Chicago Manual of Style

Writing Guidelines

  • "Use at least 11 point font for all parts of the paper.
  • Manuscripts should be printed on one side of the paper only.
  • Margins must be 1 ½ inches on all sides, and the right margin should not be justified...
  • All parts of a manuscript should be double-spaced," (APSA, 11).

Please note that there are additional instructions on abbreviations, language, spacing, etc. in the APSA Style Manual.


"Brief notes on sources appear in the text as citations, providing immediate source information without interrupting the flow of argument. A citation usually requires only the last name of the author(s), year of publication (n.d. if it is forthcoming), and (sometimes) page or chapter numbers," (APSA, 17). Parenthetical or in-text citations follow author-date citation method (i.e., author's last name and publication year) although there is some variation:

  • In a recent study of polling data (Taylor 2000) . . .
  • In 2000, Taylor evaluated polling data . . .
  • Several studies (Taylor 2000; Juarez, 2002; Peters & Lester, 2004) show that…
  • According to Taylor (2000, 24), “as society continues to undergo…”


"Notes present explanatory material and should be used sparingly. All notes should be double-spaced consecutively at the end of the manuscript,"(APSA, 22).


"Citations direct attention to the more detailed references, which provide complete source information. Include no reference that is not actually cited," (APSA, 24).

  • List all references cited in the text, alphabetically by author’s last name.
  • Note that personal communications (i.e., letters, memos, telephone conversations, interviews, E-mail, discussion groups, etc.) are cited in text or in notes only.
  • Use authors’ last names, first names (and middle initials, if available); for books, use “et al” to credit fourth through last authors.
  • Cite electronic journals, web sites and other electronic publications.
