The American Political Science Association (APSA) uses a variation of the Chicago Manual of Style citation system, concentrating on formats important to political science, with special attention given to U.S. government documents.
APSA relies on an author-date system (as used in Chicago Style) and parenthetical references within text to direct readers to the reference list.
