Chicago Style

Instructors and publishers, particularly in historical fields, often ask that you cite your sources in Chicago Style.  Citing your sources correctly prevents charges of plagiarism and also makes your paper easy to read.  Citing your sources incorrectly can make you look like a sloppy scholar. 

This worksheet provides some of the basics for citing sources correctly.  However, it does not substitute for a Chicago Style Manual.  Whenever you cite sources, you will probably need to check a style manual for correct punctuation, format, and placement.

 

Footnotes, Endnotes, and Bibliographies:
An Overview

Chicago Style dictates that each item you cite appear in an endnote or footnote.  A superscript number (found after the period of the sentence using that source) should direct the reader to the source.  The source information should be formatted the same for both footnotes and endnotes.

Some instructors require both footnotes/endnotes and a bibliography.  The bibliography is an alphabetical list of all sources cited in the document; some bibliographies even include sources not cited but useful.  Bibliographies and footnotes/endnotes are not cited in the same way!

Note Bibliographies and footnotes/endnotes are not formatted in the same way!

Footnotes and Endnotes:
Citing the Same Author Multiple Times

When you are writing a research paper, you may cite the same source multiple times.  You should not use the full citation for each time you use the source.  Only use the full citation for the first time you cite that author.  For each subsequent time you cite the same author, you should use either

An abbreviated citation contains only the author’s last name, a shortened title, and a page number.  Use an abbreviated citation when you have already cited the source in a full citation and when another source has been inserted between the full citation and the citation you are entering.

Ibid., an abbreviation for the Latin word ibidem, which means “in the same spot,” indicates that the footnote is from the same source previously cited.  If you are citing the same source but the information is on a different page, then you should use ibid. followed by a comma and the page number.

Bibliographies: A Guide to Formatting

Bibliographies are generally found at the end of documents.  They contain a list of all of the works used in the paper and often other sources that might be pertinent.  Bibliographies follow different citation rules than footnotes and endnotes, and they are generally formatted with the following information:

For a book with one author:

Author’s Last Name, Author’s First Name. Title of Book. Place of Publication: Publisher, Year of Publication.

For an article with one author:

Author’s Last Name, Author’s First Name. “Title of Article.” Title of Journal Volume, Number (Year of Publication): Page Numbers of Article.
