This guide will help you use Chicago style for citations.

About Citing Books

This guide is intended to cover only the Notes and Bibliography system for citing books.

For each type of source in this guide, both the general form and a specific example will be provided.

The following format will be used:

Full Note - use the first time that you cite a source.

Concise Note - use after the first time you cite a source.

Bibliography - use when you are compiling the Bibliography that appears at the end of your paper.

Information on citing and several of the examples were drawn from The Chicago Manual of Style (17th ed.). 

Numbers in parentheses refer to specific pages in the manual.

Book with Two or Three Authors or Editors (p. 786)

The general format below refers to a book with two authors. 

If you are dealing with two editors instead of two authors, insert the names of the editors into the place where the authors' names are now, followed by a comma and the word "eds." without the quotation marks.  The rest of the format remains the same.

Online Citation Creators

WARNING: Free online citation creators are not 100% correct. In fact, they are often wrong. It is much easier to write out the citation yourself than use these creators. 

Please ask a librarian for assistance if you are having trouble with citations.
