Citation Guide

This guide presents information and resources on APA, MLA, and Chicago styles as well as guidance on citation management programs.

Chicago Style

"The Chicago NB system is often used in the humanities and provides writers with a system for referencing their sources through footnote or endnote citation in their writing and through bibliography pages. NB system is most commonly used in the discipline of History. Properly using the NB system builds credibility by demonstrating accountability to source material." (Purdue Online Writing Lab) (Online edition)

Major Changes Between the 16th & 17th Editions

A number of changes to the Chicago Style have been introduced in the 17th edition. A few major changes that require attention are shown below.

Notes and Bibliography

  • Source citations were known as documentation in the 16th edition of CMOS and earlier.
  • Shortened citations are now preferred over ibid.

Additional changes can be found on the Chicago Manual of Style's "What's New in the 17th Edition" page.

Chicago Styles

The Chicago style allows for two different types of reference styles: the Author-Date System and the Notes and Bibliography (or Documentary-Note) Style. Traditionally, those in the humanities and social sciences (including history) use the Notes and Bibliography Style and those in the sciences use the Author-Date System.

The Author-Date System uses in-text parenthetical references followed by a corresponding References list at the end of your paper. They are used to guide the reader to your References list as they read. This System usually involves the author's last name and publication date of the cited material.

  • "Through analysis of sports injuries over a ten year period, Smith (2008) found that..."
  • "In 2008, Smith conducted an in-depth analysis of sports injuries over a ten year period to..."
  • "Sports injuries rarely cause death, however, recent research shows Traumatic Brain Injury (TBI) as the leading cause of sports injury-related death (Smith, 2008, 324-340)."

The Notes and Bibliography Style may appear more visually related to what you expect Chicago Style to resemble. This method uses a combination of footnotes and a bibliography at the end of the paper to cite material used. Citations are indicated in-text through use of inserted superscript-style numerals.

  • "Traumatic Brain Injury (TBI) has been shown to be the leading cause of sports injury-related death.1 However, we also know that sports injury-related death is rare.2"

This would be followed by a footnote at the bottom of the page. Note that in this Style, subsequent citations from the same work are shortened*:
