Chicago/Turabian Citation


Students learning Chicago/Turabian citations in class

The Chicago style of formatting citations was developed by the University of Chicago Press. The rules are outlined in the Chicago Manual of Style (CMOS). There is a shorter, easier version of Chicago style called Turabian created for students. These rules are outlined in A Manual for Writers of Research Papers, Theses, and Dissertations.

Chicago uses both the author-date citation and the notes-bibliography citation format.

Author-Date Style

This style follows the basic author-date style, which means the first two elements listed in the source citation are the author (last-name first) and the year of publication. Include the page number to direct your reader to the exact place you found the information.  Students will likely use this style rather than the notes-bibliography style.

Parenthetical Citation

In Chicago style, in-text citations are called parenthetical citations. These citations are placed within the text after a paraphrase or quotation. The parenthetical citation is a shortened version of the full citation, which is found in a reference list at the end of your paper.

To format a parenthetical citation in your paper, follow these guidelines:

  1. After quoting or paraphrasing from a source, place the author’s last name and the year of publication within parentheses.
  2. Do not place a comma between the first two elements.
  3. Include the page number(s).
  4. Place a comma after the year of publication to separate the page number(s).

For multiple authors, follow this format:

(Berkman, Bauer, and Nold 2011, 7-10)

Author-Date Reference Source Citation

The full source citation is arranged in a reference list at the end of your paper. This source citation contains all the data needed to guide your reader to the exact source you used for your research.


  • Author
  • Date
  • Title
  • Publication
  • Publisher
  • Location



Unger, Roberto Mangabeira, and Lee Smolin. 2014. The Singular Universe and the Reality of Time: A Proposal in Natural Philosophy. Cambridge: Cambridge University Press.


Include the doi, if available


Lamont, Michele. 2012. “Toward a Comparative Sociology of Valuation and Evaluation.” Annual Review of Sociology 38 (August): 201-22. https://doi.org/10.xxxxxxxxxxx.


For the first author, list last name first. Second author is listed by first name, last name

Arranging Author-Date References

Your parenthetical citations point your reader to a full source citation, listed alphabetically in a reference list at the end of your paper. There are a few exceptions, for example, biblical or classical parenthetical citations do not need a reference list citation.

Although bibliographies can be sectioned by types of works, your reference list is simply an alphabetical list of your source citations. Some other guidelines for arranging your reference list include:

  1. Alphabetize by author’s last name.
  2. If no author, use the editor or title of work.
  3. Spell out edited by or translated by.
  4. Abbreviate editor, translator, volume, number.

Use the 3 em dash for multiple works by the same author, if your teacher instructs you to do so.

After you’ve arranged your reference list, double-check your paper to make sure all your parenthetical citations have a matching source citation.

Notes-Bibliography Style

The Chicago/Turabian notes-bibliography style is different than the author-date style as it uses numbered notes within the text. These numbers link to either footnotes or endnotes. These notes are then complied in a full works consulted bibliography at the end of the article or book. In some cases, notes contain enough source information that there is no need for a full bibliography.

Parenthetical Citations

Rather than placing notes within parenthetical citations, a superscript number is placed next to cited information within the text. That number matches with the note at the bottom of the page or end of the chapter or paper. The matching footnote or endnote number is not placed as superscript.


A footnote or endnote lists these elements:

  • Author,
  • Date,
  • Facts of publication.

To format a note:

  • Use commas to separate the elements
  • Enclose facts of publication in parentheses
  • List authors’ names by first name, last name
  • Capitalize titles using headline style
  • Italicize titles of books, journals
  • Use quotation marks around chapter or article titles


Gabriel Garcia Marquez, Love in the Time of Cholera, trans. Edith Grossman (London: Cape, 1988), 242-55.


If you use the same note later in the paper, shorten it as follows:

Garcia Marquez, Cholera, 33.


The use of ibid. is discouraged in Chicago style; however, follow your teacher’s instructions.

Note: Notes may contain commentary along with the source elements.

Bibliographic Source Citations

To create the full source citation in the bibliography, include all elements in this format:

Garcia Marquez, Gabriel. Love in the Time of Cholera. Translated by Edith Grossman. London: Cape, 1988.


Include the doi or url for sources accessed online.


Liu, Jui-Ch’i. “Beholding the Feminine Sublime: Lee Miller’s War Photography.” Signs 40, no. 2(Winter 2015): 308-19. https://doi.org/10.xxxxxxxxxx.


Creating a Bibliography

A bibliography contains all the works you’ve consulted for your research. You may section your bibliography by types of works, authors or any other method that will help your reader.

Arrange the bibliography alphabetically by the first element of the source citation. Usually this is the author, but it may be the title of the work. Ignore articles, such as A, An, The in titles.

You may use the 3-em dash system for multiple works by the same author; however, check with your instructor.

You’ll probably notice the notes system while doing your research as extensive texts on history and other humanities subjects often use notes-bibliography. These notes are helpful in your research process as they can lead you to interesting materials for your own research.

As always follow your assignment rubric, double-check your formatting and make sure to include all the sources you consulted in your bibliography.
