The Chicago Manual of Style is published and created by the University of Chicago Press for publishers, scholars, and students. The first version of the manual was published in 1906 and the 16th, most recent, edition was published in August 2010. The Chicago Manual includes formatting guidelines on the use of the English language for writers in all disciplines, but the citation style is used primarily by those in the humanities.

Turabian style was created by Kate L. Turabian (1893-1987), a secretary at the University of Chicago who worked with the graduate school dissertations and edited official publications for the university. Turabian style closely follows the 15th ed. Chicago Manual of Style, but with slight adaptations specifically for students and researchers.

Note: There are two formatting styles for the Chicago Manual of Style. The Notes-Bibliography system uses footnotes. The Author-Date system uses parenthetical citations in the text.
