The Chicago Manual of Style (CMS) is a comprehensive guide to writing, editing, and publishing, widely regarded as a standard in the field of academic and professional publishing across many disciplines, including the arts, humanities, social sciences, and sciences. First published by the University of Chicago Press in 1906, it provides detailed instructions on grammar, punctuation, formatting, citation, and various other aspects of writing. The CMS is known for its thoroughness and flexibility, offering two documentation systems: the notes and bibliography style, commonly used in humanities disciplines, and the author-date style, preferred by the sciences and social sciences.
Chicago Style differs from MLA and APA formats in the specifics of document formatting and citations but also in that it allows for footnotes.
