Citing Sources

Referencing, avoiding plagiarism, and presentation of the Chicago Style

The "Notes and Bibliography" System

This is the first of Chicago's two citation systems. Bibliographic citations are given in notes (footnotes or endnotes), with or without a full bibliography at the end of the text.

Notes
First Name Last Name or Institution, Title: Subtitle; Second subtitle. Edition (if not the first). Volume, total number of volumes if multivolume work is referred to as a whole, or number of the volume cited. Title of the volume, if applicable. Series title, and volume number within series if series is numbered (Place of publication: Publisher, year of publication), Page number(s) if applicable.

Example
Thomas Piketty, Capital in the Twenty-First Century. (Cambridge: The Belknap Press of Harvard University Press, 2014), 56-68.

Bibliography
Last Name, First Name or Institution. Title: Subtitle; Second subtitle. Edition. Series title and volume number within series. Place of publication: Publisher, date of publication.

Example 1
Piketty, Thomas. Capital in the Twenty-First Century. Cambridge: The Belknap Press of Harvard University Press, 2014.

Example 2 (the author is an institution)

Organisation Mondiale du Commerce and Organisation Mondiale de la Santé. Les accords de l’OMC et la santé publique: étude conjointe de l’OMS et du secrétariat de l’OMC. Geneva: Organisation Mondiale de la Santé: Organisation Mondiale du Commerce, 2002.

Example 3 (multiple authors)
Note: First Name Last Name Author 1 and First Name Last Name Author 2.
Bibliography: Last Name, First Name Author 1 and First Name Last Name Author 2.
The name of the first author is inverted in the bibliography, because the references are arranged alphabetically.

Steven, Graeme C. S. and Rohan Gunaratna. Counterterrorism: a Reference Handbook. Contemporary world issues.  Santa Barbara, Calif.: ABC Clio, 2004.

If there are more than 3 authors, all names are usually given in the bibliography. In a note, only the name of the first author is included, followed by “et al.” with no intervening comma.

Example 4 (editor in place of author)
Use the abbreviation ed. or eds:

Newman, Mark, Albert-László Barabasi and Duncan J. Watts, eds. The Structure and Dynamics of Networks. Princeton studies in complexity. Princeton: Princeton University Press, 2006.

The citation must follow the general recommendations for citing books, and include the format of the e-book (e-pub, PDF...) and the URL if the book was consulted online at the end of the citation.

Example (bibliography):
Grainger, John D., The Battle for Syria, 1918-1920. Woodbridge: Boydell and Brewer, 2013. PDF. www.jstor.org/stable/10.7722/j.ctt24hfx6

Citations of unpublished interviews that are part of the research process should include: the names of both the interviewee and the interviewer; brief identifying information, if appropriate; the place and/or date of the interview (who may simply be "the author"); the location of the transcript or recording.

If the bibliography includes all the works cited in the notes, the notes citations may be shortened. Subsequent citations to sources already given in full should be shortened wherever possible.  The most common abbreviation consists of the author's surname and the main title of the cited work, usually abbreviated if it is longer than four words.  

Example
1. Jean-Paul Gourévitch, La France en Afrique: cinq siècles de présence;  vérités et mensonges (Paris: Acropole, 2006).
