Turabian vs. Chicago Style: Which does your Dissertation or Thesis need?

Turabian and Chicago style are closely related, but they are not interchangeable in every respect. Both offer guidance on citations and manuscript preparation, yet they serve different audiences. If you are writing a doctoral dissertation, the right choice depends on your university’s requirements and your department’s expectations.

This guide explains the differences between Turabian and Chicago style and how to determine which manual to follow.

What Is Chicago Style?

Chicago style refers to The Chicago Manual of Style, a reference manual used in publishing and academic writing. It covers citation practices, manuscript preparation, grammar, and other editorial conventions.

Chicago offers two citation systems:

Notes and Bibliography: Uses footnotes or endnotes, usually alongside a bibliography. It is common in history and other humanities disciplines.
Author-Date: Uses parenthetical citations in the text and a reference list. It is used in some social sciences and related fields.

The appropriate system depends on the discipline, publication, or institution’s requirements.

What is Turabian Style?

Turabian style refers to A Manual for Writers of Research Papers, Theses, and Dissertations by Kate L. Turabian. Developed with student research in mind, it adapts Chicago’s guidance for academic papers, theses, and dissertations.

Turabian includes the same two broad citation systems: Notes and Bibliography and Author-Date. It also provides practical guidance for preparing longer academic documents, including their organization and presentation.

In simple terms, Turabian is a student-oriented adaptation of Chicago style. The two manuals overlap substantially, but they should not be treated as identical in every formatting detail.

Key differences between Turabian and Chicago Style

Audience and purpose. Chicago serves a broad publishing and editorial audience. Turabian focuses on students preparing research papers, theses, and dissertations.

Dissertation formatting. Turabian addresses student research documents directly. However, your university may have its own rules for title pages, approval pages, abstracts, tables of contents, and other front matter. Neither manual should be assumed to replace those institutional requirements.

Headings and document structure. Both manuals provide guidance on organizing and presenting a manuscript. The specific requirements you must follow depend on the manual, its edition, and your institution’s dissertation guidelines.

Citation practices. Turabian and Chicago citation formats are closely related. Even so, you should follow the system and edition required by your institution rather than assume that every detail is identical.

Which Style should your Dissertation or Thesis follow?

Your university’s requirements should determine your choice. To establish which manual applies:

Find your graduate school’s official dissertation or thesis formatting guidelines.
Identify the required style manual and edition, if specified.
Check whether your department or discipline requires a particular citation system.
Ask your dissertation chair or graduate school office if the instructions are unclear.

Some institutions specify Turabian, while others require Chicago or provide their own formatting rules alongside a designated citation system. Do not assume that one applies simply because your research falls within a particular discipline.

What If Your University Specifies Chicago Style?

Follow the instructions as written. If your university requires Chicago style, check whether it specifies Notes and Bibliography or Author-Date. Use the relevant guidance from the required edition, along with your institution’s rules for dissertation-specific elements.

Do not automatically substitute Turabian simply because you are writing a dissertation. If you are unsure whether Turabian is acceptable, confirm this with your department or graduate school.

Common Mistakes to Avoid

Using the wrong edition: Check which edition your institution requires rather than assuming the newest edition is mandatory.
Mixing citation systems: Choose the required system and apply it consistently.
Relying on citation generators without checking: Automated tools can introduce errors or apply the wrong format. Verify citations against the required manual.
Ignoring institutional instructions: University requirements may specify details that differ from a style manual. Follow the institution’s stated rules when preparing your submission.
