Chicago Style Guide


The Notes and Bibliography system of citation is used in the humanities, and especially in History courses. An excellent guide can be found on the Chicago Manual of Style website:

This guide provides examples of how to cite sources commonly used by Selkirk College students.

When you use another person's ideas in your paper, even if you put the author's ideas into your own words, you must cite (i.e. credit) the source.

  • Endnotes or footnotes are credits in the body of a paper.
  • A bibliography is a complete list of all the sources consulted in the course of writing a paper. The bibliography begins on a separate page, entitled “Bibliography,” at the end of the paper.
  • Short notes. If you include a bibliography then you can use short notes in your paper. Only short notes are shown in this guide. See the Chicago Manual for examples of full notes.


N:    Note (short)
B:    Bibliographic citation
Numbering in italics refers to sections in The Chicago Manual of Style (print ed.)



1, 2 or 3 Authors 14.76

N: List all the authors by last name
B: List all the authors.  Only the first author’s name is inverted.

4 to 10 Authors

N: List the first author by last name, followed by et al.
B: List all the authors.  Only the first author’s name is inverted.

No Author 14.79
Begin the citation with the title

Organization as Author 14.84
If an organization (group) is both the author and the publisher, list them as both in the bibliography


Italics. Use italics for the title of a book, journal, magazine, newspaper or video. “Quotation marks.” Use quotation marks around the titles of article, chapters, poems
and other works that are part of a larger work.



Electronic Sources 14.12 – 14.13
Give one of the following dates:
▪    Publication date
▪    Last modified, revised or updated
▪    Date accessed (only if neither of the above are given)


Page Numbers


Give the page number(s) from which the cited information was taken.


No Page Numbers
Electronic sources such as e-books or online newspapers may not include page numbers. A chapter or paragraph number or a section heading may be given instead.



Uniform Resource Locators


A URL should be included for sources found online. The order of preference is:

▪    DOI (digital object identifier). Use the DOI if one is given. A DOI forms a permanent URL that begins https://doi/org/

▪    Persistent URL. For sources from a library database, use the persistent URL (if there is no DOI). Persistent URLs are also called permalinks, stable URLs, or document URLs.

▪    URL. For sources found on the Internet, give the URL from the browser address bar (if no other URL is provided).



Line Spacing
▪    Double space: The body of the paper and between entries in the notes and the bibliography.
▪    Single space: Within entries in the notes and bibliography.


Font. 12 pt., serif (such as Times New Roman)
