Chicago Style Guidelines
In academic writing, it is important to give credit to authors whose research or ideas you use in writing a paper. Proper citations also allow the reader to easily retrieve additional information on the subject.
Papers written for history and some other humanities classes often use a footnote or endnote system called The Chicago Manual of Style. In addition, CMS papers may require a reference page; in CMS style, this is titled the “bibliography.”
Introducing sources in-text
On first reference of an author, use the author's full name. When quoting sources, avoid “dropped quotes” by using a “signal phrase” that identifies the author, source, and /or context for the cited material. For example, Garry Wills writes that “we live in a different America” because of the Gettysburg Address. Generally, CMS uses the present tense (writes) or present perfect tense (has written). However, as noted by Diana Hacker in A Writer's Reference, “If you have good reason to emphasize that the author's language or opinion was articulated in the past…the past tense is acceptable.”
In Chicago Style there are no strict guidelines as to when to indent longer quotations. You may want to indent quotes more than four or five lines long for added emphasis; quotes longer than eight lines should always be indented.
In the typical footnote or endnote style, there are three citation points necessary in a CMS paper:
“The United States conditioned its financial and political support for the conservative-moderate anti-Pinochet groups on their willingness to break ties with the left and participate in an electoral calendar outlined by the dictatorship.” 1
After the first reference to a work, only an abbreviated reference is necessary for additional in-text references.

- Bibliographic Entry

How to Cite Various Types of Sources
Note that the first entry below is the format for a footnote/endnote, and the second entry is the format for a bibliography. In a footnote/endnote entry, indent the first line; in a bibliography entry, use a “hanging indent” in which the second and subsequent lines are indented.
Also, place parentheses around the publisher's information in the footnote/endnote, but do not use them in the bibliographic entries.
