Chicago Citation & Style Guide

About Chicago

Chicago style, most frequently used in history and the social sciences, is specific formatting style that that students and scholars use to write papers and cite sources. Information here is taken from the The Chicago Manual of Style (16th ed.) which may be consulted for questions not addressed here. Purdue University's Online Writing Lab is also an excellent resource.

Please note that Chicago style requires the use of one of two different documentation systems. The first, called Notes and Bibliography, is presented here and in the handout below, uses notes (footnotes or endnotes or both) and usually a bibliography. For the Author-Date system consult The Chicago Manual of Style or meet with a librarian.
