Numbers in parentheses refer to specific pages in the Chicago 17th Edition manual.
Numbering
Note numbers in text are set as superscript numbers (p. 751).
At the bottom of the page, the note numbers are normally full size and followed by a period (p. 751).
Notes should be numbered consecutively, beginning with 1 (p. 756).
Tip: Use your word processor's "footnote" feature to assist with formatting.
Full Note vs. Shortened Note
The first note referring to a work must be a full note, but subsequent citations for that same work can be shortened. The shortened form should include just enough information to remind readers of the full title or lead them to the bibliography; usually the last name of the author(s), the key words of the main title, and the page number. Check with your instructor to determine whether this shortened form is acceptable. (p. 757-761)
Example:
1. Salman Rushdie, The Ground beneath Her Feet (New York: Henry Holt, 1999), 25.
2. Valerie Bunce, "Rethinking Recent Democritization: Lessons from the Postcommunist Experience," World Politics 55, no. 2 (2003): 168, http://www.jstor.org/stable/25054217.
3. Rushdie, The Ground beneath, 28.
Consecutive footnotes for the same work
When citing the same source in multiple footnotes one after the other, cite the source in full the first time, and then use the abbreviated form for all subsequent citations until another source is cited (p. 759-760).
Example:
1. Rushdie, The Ground beneath, 25.
2. Rushdie, 28.
URLs
When the note entry includes a URL that must be broken at the end of a line, the break should be made after a colon of double slash (//); before a single slash (/), a tilde (~), a period, a comma, a hyphen, an underline (_), a question mark, a number sign, or a percent symbol; or before or after an equal sign or an ampersand (p. 750).
Even if you put information in your own words by summarizing or paraphrasing, you must still use a footnote just as you would with a direct quotation. All the information required in the footnote for a paraphrased sentence is the same as if you were using a direct quotation.
