What is APA style?
APA stands for the American Psychological Association. It is the citation style used in most of
the social sciences as well as some of the natural sciences.
Official APA Style Manual at CSUSM Library
This is the official APA manual published by the American Psychological
Association. Though the 7th edition of the Publication Manual of the American Psychological Association was
released in October 2019, we are currently providing information and links to the 6th edition. This is
because the American Psychological Association expects students and professors to transition to this
new edition in the spring of 2020 or thereafter. The CSUSM library is awaiting the delivery of the new
guides and the transition of other reliable sources to the 7th edition before updating its own citation
guide. If you are required to use the 7th edition prior to our updating our APA page, please go directly to
the APA's Style and Grammar
Guidelines website or contact a librarian directly for assistance.

A DOI is a special number that identifies each unique article in a database.
