One of the newer style formats, ASA style was created by the American Sociological Association starting in 1992, finally being published in 1996. This style "...provides guidance for writing, submitting, editing, and copyediting manuscripts for ASA journals and other publications that follow ASA’s style. The newest edition includes expanded information on the use of electronic, digital, and social media sources, as well as guidance for online manuscript submissions." Similar to Chicago's 'author-date' format.
