American Political Science Association (APSA)
*Note: Many universities' websites and other online help exist for APSA. Use caution when referencing any style resources outside of the published APSA manual.
"The most recent APSA Style Manual (2006) asks writers to use the parenthetical documentation system in the Chicago Manual of Style (author-date style, not notes style) for documentation in political science writing. For a brief overview, see pages 17 and following in the APSA manual." –
For that reason, you may be assigned to the Chicago manual, but we have added the APSA manual to our site for handy access.
