A full guide to citation style can be found here (Some entries are below for ease of reference).
All bibliography entries should be arranged alphabetically by author surname. In case of multiple authors, arrange by first author surname.
APSA uses a parenthetical author-date citation style:
At the end of the sentence containing cited material the citation should appear: "... (Wilson, 2023)."
In the bibliography at the end of the paper, the citation for a monograph should appear:
Wilson, Greg S. 2023. A full-length exposition about a random topic. Alamosa, CO: Adams State University Press.
