Chicago Manual of Style
The Chicago Manual of Style is the offical guide of Chicago citation formatting. You can find the manual at the reference desk and in the reference section of the library's collection.
Chicago Citation Style is also called Turabian Citation Style. This citation style is less common than MLA and APA citation styles. Use the links below to help citing your sources and formatting your paper in Chicago Style.
Chicago Style format for Bibliography
When you use outside sources, you will need to create a Bibliography that tells your reader all the information they need to go find the source themselves if they want to. Commonly used sources include:
Carley, Michael J. 1939: The Alliance That Never Was and the Coming of World War II. Chicago: Dee, 1999.
Bharadwaj, Parag, and Katherine T. Ward. “Ethical Considerations of Patients with Pacemakers.” American Family Physician 78 (2008): 398-99.
Satalkar, Bhakti. “Water Aerobics.” Buzzle.com. July 15, 2010. www.buzzle.com.
Chicago Style Footnotes
The style of Chicago/Turabian requires footnotes rather than in-text or parenthetical citations. Footnotes or endnotes acknowledge which parts of their paper reference particular sources. Generally, you want to provide the author’s name, publication title, publication information, date of publication, and page number(s) if it is the first time the source is being used. Any additional usage, simply use the author’s last name, publication title, and date of publication.
Footnotes should match with a superscript number at the end of the sentence referencing the source. You should begin with 1 and continue numerically throughout the paper. Do not start the order over on each page.
For example: 1. Henry James, The Ambassadors (Rockville: Serenity, 2009), 34-40.
When citing a source more than once, use a shortened version of the footnote: 2. James, The Ambassadors, 14.
Citing sources with more than one author
If there are two or three authors of the source, include their full names in the order they appear on the source. If there are more than three authors, list only the first author followed by “et al.” You should list all the authors in the bibliography;
4. John K. Smith, Example Book (New York: Scholastic, 2010), 65.
Citing sources with no author
It may not be possible to find the author/contributor information; some sources may not even have an author or contributor- for instance, when you cite some websites. Simply omit the unknown information and continue with the footnote as usual:
Citing a part of a work
When citing a specific part of a work, provide the relevant page or section identifier. This can include specific pages, sections, or volumes. If page numbers cannot be referenced, simply exclude them. Below are different templates:
Chapter in a book:
Introduction, afterword, foreword, or preface:
Article in a periodical:
Citing online sources
Generally, follow the same principals of footnotes to cite online sources. Refer to the author if possible and include the URL.
19. Bhakti Satalkar, “Water Aerobics,” http://www.buzzle.com, (July 15, 2010).
Citing online sources with no author
If there is no author, use either the article or website title to begin the citation. Be sure to use quotes for article titles and include the URL.
