Notes
Notes can be footnotes (each one appearing at the bottom of the page on which its citation appears) or endnotes (in a list on a separate page at the end of the text). (Check your instructor’s preference.) Indent the first line of each note one-half inch and begin with a number, a period, and one space before the first word. All remaining lines of the entry are flush with the left margin. Single-space footnotes and endnotes, with a double space between entries.
Use superscript numbers (1) to mark citations in the text. Place the superscript number for each note just after the relevant quotation, sentence, clause, or phrase. Type the number after any punctuation mark except the dash, and do not leave a space before the superscript. Number citations sequentially throughout the text. When you use signal phrases to introduce source material, note that Chicago style requires you to use the present tense (citing Bebout’s studies, Meier points out . . .).
IN THE TEXT
Sweig argues that Castro and Che Guevara were not the only key players in the Cuban Revolution of the late 1950s.19
IN THE FIRST NOTE REFERRING TO THE SOURCE
19. Julia Sweig, Inside the Cuban Revolution (Cambridge, MA: Harvard University Press, 2002), 9.
After giving complete information the first time you cite a work, shorten additional references to that work: list only the author’s last name, a comma, a short version of the title, a comma, and the page number. If you refer to the same source cited in the previous note, include only the author's last name and the page number.

Bibliography
Begin the list of sources on a separate page after the main text and any endnotes. Continue numbering pages consecutively. Center the title Bibliography (without underlining, italics, or quotation marks) one inch below the top of the page. Begin each entry at the left margin. Indent the second and subsequent lines of each entry one-half inch, or five spaces.
List sources alphabetically by authors’ last names or by the first major word in the title if the author is unknown. Italicize titles of books and periodicals, and enclose titles of short works in quotation marks. See an example of a Chicago-style bibliography.
In the bibliographic entry, include the same information as in the first note for that source, but omit the page reference. Give the first author’s last name first, followed by a comma and the first name; separate the main elements of the entry with periods rather than commas; and do not enclose the publication information for books in parentheses.
