Turabian Citation Style: A Complete Guide with Examples

The Turabian citation style, derived from Kate L. Turabian's A Manual for Writers of Research Papers, Theses, and Dissertations, is a widely used academic citation system. It's particularly common in the humanities and social sciences. Turabian offers two primary systems: the Notes-Bibliography system and the Author-Date system. Understanding which one to use and how to implement it correctly is key to academic integrity.

Choosing the Right Turabian System

Your instructor or publisher will usually specify which system you need to use. However, generally:

  • Notes-Bibliography System: This is the more traditional and common system in the humanities (literature, history, arts). It uses footnotes or endnotes to cite sources and a bibliography at the end of the paper.
  • Author-Date System: This system is more common in the social sciences (sociology, psychology, political science). It uses parenthetical in-text citations and a reference list at the end.

The Notes-Bibliography System: In-Depth

This system involves two main components: in-text notes and a bibliography.

In-Text Notes (Footnotes or Endnotes)

When you refer to a source in your text, you'll place a superscript number after the relevant sentence or clause. This number corresponds to a note at the bottom of the page (footnote) or at the end of the document (endnote).

First Reference to a Source: This note will contain full bibliographic information.

  • Book Example:

¹ Jane Doe, The Art of Writing (New York: Penguin Books, 2020), 45.

  • Journal Article Example:

² John Smith, "The Evolution of Citation Styles," Journal of Academic Writing 35, no. 2 (2019): 112.

  • Website Example:

³ "About Turabian," The University of Chicago Press, accessed October 26, 2023, https://www.press.uchicago.edu/books/turabian/index.html.

Subsequent References to the Same Source: If you cite the same source multiple times, you can shorten the note.

  • Shortened Note Example:

⁴ Doe, Art of Writing, 78. ⁵ Smith, "Evolution of Citation Styles," 115.

If you have multiple works by the same author, you'll need to include a shortened version of the title in subsequent citations.

Bibliography

The bibliography is an alphabetical list of all the sources you cited in your paper. It appears at the end of your document. The formatting is similar to the first note reference, but with some key differences:

  • The author's last name comes first.
  • Periods are used to separate elements, not commas.
  • There are no superscript numbers.
  • Book Example:

Doe, Jane. The Art of Writing. New York: Penguin Books, 2020.

  • Journal Article Example:

Smith, John. "The Evolution of Citation Styles." Journal of Academic Writing 35, no. 2 (2019): 110-130.

  • Website Example:

"About Turabian." The University of Chicago Press. Accessed October 26, 2023. https://www.press.uchicago.edu/books/turabian/index.html.

The Author-Date System: In-Depth

This system uses parenthetical citations within the text and a reference list at the end.

In-Text Citations

When you refer to a source, you include the author's last name and the year of publication in parentheses. If you mention the author's name in your sentence, you only need the year.

  • Book Example:

(Doe 2020) Jane Doe argues that citation styles have become increasingly complex (Doe 2020).

  • Journal Article Example:

(Smith 2019) Smith's research indicates a shift in academic writing practices (Smith 2019).

  • Website Example:

(The University of Chicago Press 2023) The official website provides guidelines for Turabian (The University of Chicago Press 2023).

If you need to cite a specific page or range of pages, include that information after the year, separated by a colon.

  • Page Number Example:

(Doe 2020, 45) (Smith 2019, 112)

Reference List

The reference list is an alphabetical list of all the sources cited in your paper. It appears at the end of your document. The formatting is similar to the in-text citation, but with full bibliographic details.

  • Book Example:

Doe, Jane. 2020. The Art of Writing. New York: Penguin Books.

  • Journal Article Example:

Smith, John. 2019. "The Evolution of Citation Styles." Journal of Academic Writing 35, no. 2: 110-130.

  • Website Example:

The University of Chicago Press. 2023. "About Turabian." Accessed October 26, 2023. https://www.press.uchicago.edu/books/turabian/index.html.

Key Formatting Points for Turabian

Regardless of the system, some formatting rules are consistent:

  • Margins: Typically 1-inch margins on all sides.
  • Font: Use a readable font like Times New Roman or Arial, usually 12-point.
  • Spacing: Double-space your entire paper, including notes and bibliography/reference list.
  • Page Numbers: Include page numbers, usually in the header.
  • Title Page: Often required, containing the paper title, your name, course information, and date.

Common Pitfalls to Avoid

  • Inconsistency: The most common mistake is not being consistent with your chosen system and formatting.
  • Missing Information: Double-check that all necessary bibliographic details are present for each source.
  • Incorrect Punctuation: Pay close attention to periods, commas, and parentheses.
  • Oversimplification: Don't assume a quick online citation generator will get every detail perfect. Always cross-reference with a style guide.

Navigating citation styles can feel daunting, but with practice and attention to detail, you'll master it.

Always refer to the latest edition of A Manual for Writers of Research Papers, Theses, and Dissertations or your instructor's guidelines for the most accurate and up-to-date information.
