Chicago Style Citation Quick Guide
First Page Headings (Double-spaced). A separate title page is not necessary.
Left side: Right side:
Your Name Last name, page number
On the right side of the page, at the top, type your last name and the page number.
Chicago papers do not use in-text citations like those found in MLA. Instead, sources are cited in numbered footnotes at the bottom of that page. Footnotes follow any information that is considered uncommon knowledge whether directly quoted, summarized or paraphrased. Any direct quotation must also have a corresponding footnote.
Notes and Bibliography (also known as the Chicago NB format)
Footnotes go at the bottom of the page on which the source is referenced.
Use a superscript number in the text of the paper, at the end of the sentence in which the source is referenced, after the punctuation. Footnoted sources must also be listed in a separate bibliography. See example below for footnotes for book sources.
1. Zadie Smith, Swing Time (New York: Penguin Press, 2016), 315–16.
2. “About Yale: Yale Facts,” Yale University, accessed May 1, 2017, https://www.yale.edu/about-yale/yale-facts.
Shortened footnotes (These are used when you have already fully footnoted the source one time. Any subsequent use of the same source will have a shortened footnote format.)
3. Smith, Swing Time, 320.
4. “Yale Facts.”
The bibliography must include every source you cited within your footnotes AND any other sources you consulted during your research. The bibliography is its own page and it goes at the end of the paper. Bibliography entries are to be in alphabetical order.
Below are two websites that you may want to consult for source-specific footnote and bibliography entry formats.
