APSA Citation Style: Parenthetical Citations

This libguide provides a brief overview on the APSA Citation Style for the political science discipline.

Parenthetical Citations

  • Brief notes on sources appear in the text as citations, providing immediate source information without interrupting the flow of the manuscript. A parenthetical citation is set off at the end of a sentence by parentheses.
  • The usual format, which refers to the work and the overall ideas of the work as a whole, requires only the last name of the author(s), editor(s), or translator(s) and the year of publication (n.d. if there is not date, forthcoming if it is forthcoming).
  • The terms ed. or eds. and trans., which are abbreviated in the reference list, are omitted from parenthetical citations.
  • No comma should be placed between the last name and the year of publication. 
  • The page numbers can be cited as either inclusive or nonconsecutive page numbers.
  • No comma should be placed between the last name and the year of publication, but a comma should be placed after the year before page or chapter numbers (APSA 2018, 41-42).

  • With two or three authors, cite all names each time. Use and, not an ampersand (&). For four or more, use et. al. 

(Collins and Jones 2021)   (Collins, Maxx, and Jones 2021, 42)   

  • When multiple sources are cited together, they are included in the same parentheses, but separated by semicolons. They should be alphabetized.

(Collins 2021; Simoun 2018; Ynarez 2015)
