Chicago Stylefrom Purdue University - The Chicago Manual of Style (CMS) covers a variety of topics from manuscript preparation and publication to grammar, usage, and documentation and has been lovingly called the “editors’ bible.” The material in this resource focuses primarily on one of the two CMS documentation styles: the Notes-Bibliography System (NB), which is used by those in literature, history, and the arts. The other documentation style, the Author-Date System, is nearly identical in content but slightly different in form and is preferred in the social/sciences.
