The fifth edition of the ASA Style Guide is the authoritative reference for writing, submitting, editing, and copyediting manuscripts for ASA journals and other publications following ASA's unique format. This revised, expanded edition features guidelines for the most common situations encountered by authors and editors. New features include revisions to reference formatting and additional information on grammar. In addition, updated reference examples, including citing social media sources and journal articles posted online ahead of print, are included in this new edition. This guide also has been updated based on the 16th edition of the Chicago Manual of Style, on which much of ASA style is based.
