Chicago Style (17th Edition) Citation Guide: Introduction

Who should use Chicago Style?

Chicago style is the preferred citation style for history and theology.

Note: UP typically uses the "notes and bibliography" format of Chicago style, not the "author date" format.

What is Chicago Style?

Chicago style was created by the University of Chicago. It is a set of rules for publications, including research papers.

In Chicago style, you must cite sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:

  1. In the body of your paper where you add a footnote (which appears in the footer at the bottom of the page).
  2. In the bibliography at the end of your paper.
