Chicago Manual of Style, Author-Date or Parenthetical style

The Chicago Manual of Style includes an author + date + page number system for parenthetical in-text citations, which is a more formal referencing system. This consists of parenthetical citations within the text of the form (Author Year) or (Author Year, page #), with a bibliography (end references, works cited) at the end with full information on the sources cited. The parenthetical author-date system is used in many humanities fields (e.g., history, philosophy, international studies), business, and sometimes in sciences and social sciences. This formal author-date-page system is illustrated below.

There also exists a more semi-formal notes and bibliography style, consisting of footnotes and a works cited section. This is used in humanities publications (e.g., less formal or less academic publications in literature, history, arts). The CM system, including the notes + bibliography style, can handle some more unusual source types that do not fit well in an author-date system such as the APA. For more details on the CM author-date or note-bibliography systems, refer to the CM website ( In academic writing in history studies, the Turabian style may be used, which is very similar to CM. but there is also a footnote / endnote plus bibliography format.
