The American Anthropological Association (AAA) is the largest organization for professional anthropologists in the world. They have over 10,000 members. The AAA was founded in 1902 and publishes 22 journals. The AAA style guide is used to write papers by its members for its journals.
As of September 9, 2015 , the AAA style guide is now the same as the Chicago Manual of Style. Therefore, any anthropologists who are used to using the AAA style should now go to the Chicago style guide that is on this site or directly to the Chicago Manual of Style online: http://www.chicagomanualofstyle.org/home.html and their quick citation guide: http://www.chicagomanualofstyle.org/tools_citationguide.html
