Understanding citation styles is fundamental to academic integrity and effective communication in scholarly writing. Among the most widely used systems are Chicago and Turabian. While often spoken of interchangeably, these two styles, though intimately related, serve distinct purposes and audiences. This guide will clarify their relationship, highlight their key differences, and provide practical advice on choosing and applying the correct style for your work.
The Core Relationship: Chicago's Student Sibling
At its heart, Turabian is a streamlined, student-focused version of the Chicago Manual of Style (CMOS). Both originate from the University of Chicago Press. Think of it this way: CMOS is the comprehensive, authoritative guide for professional scholars, editors, and publishers across various disciplines. It covers everything from grammar and punctuation to citation and manuscript preparation for publication.
Turabian, specifically Kate L. Turabian's A Manual for Writers of Research Papers, Theses, and Dissertations, distills the core principles of CMOS into a more accessible and prescriptive format tailored for students. It provides clear, step-by-step instructions for formatting academic papers, theses, and dissertations, addressing the specific needs of student writers who are learning how to cite and present research for their courses.
Crucially, the underlying citation rules for specific source types (e.g., how to cite a book, a journal article, or a website) are nearly identical in both Chicago and Turabian for their respective citation systems. The primary differences lie in the scope of their guidance and the specific formatting requirements for the overall manuscript.
Two Primary Citation Systems: Notes-Bibliography and Author-Date
Both Chicago and Turabian offer two main citation systems:
- Notes-Bibliography (NB) System: Predominantly used in the humanities (history, literature, arts).
- Author-Date (AD) System: Primarily used in the social sciences and natural sciences.
The choice between these two systems is usually dictated by your discipline or your instructor's preference, not by whether you're using Chicago or Turabian. Within each system, the actual format for citing sources is largely consistent across both manuals.
1. The Notes-Bibliography (NB) System
The NB system employs footnotes or endnotes to cite sources within the body of the text and includes a comprehensive bibliography at the end of the document.
When to Use It:
- History
- Literature
- The Arts
- Religious Studies
- Other humanities fields where detailed textual commentary or multiple citations per point are common.
Key Features:
- Footnotes/Endnotes: A superscript number in the text corresponds to a numbered note at the bottom of the page (footnote) or at the end of the paper (endnote). The first citation of a source includes full publication details; subsequent citations are shortened.
- Bibliography: A complete, alphabetized list of all sources cited in the paper, providing full publication information.
Examples (Chicago/Turabian NB System):
In-text Footnote: ¹ Michael Pollan, The Omnivore's Dilemma: A Natural History of Four Meals (New York: Penguin Press, 2000), 99–100. ² Pollan, Omnivore's Dilemma, 105.
Bibliography Entry: Pollan, Michael. The Omnivore's Dilemma: A Natural History of Four Meals. New York: Penguin Press, 2000.
Key Distinction within NB: While the citation format is the same, Turabian often provides more explicit guidance on the placement and formatting of footnotes/endnotes within a student paper, whereas Chicago's guidance is broader, assuming a professional editorial context.
2. The Author-Date (AD) System
The AD system uses parenthetical citations within the text, typically including the author's last name, publication year, and sometimes a page number. A separate "References" list at the end of the paper provides full bibliographic details.
When to Use It:
- Social Sciences (sociology, political science, psychology)
- Natural Sciences (biology, chemistry, physics)
- Some interdisciplinary fields.
Key Features:
- Parenthetical Citations: Brief citations enclosed in parentheses appear directly in the text, usually at the end of a sentence or clause.
- Reference List: A complete, alphabetized list of all sources cited, titled "References."
Examples (Chicago/Turabian AD System):
In-text Parenthetical Citation: (Pollan 2000, 99–100) According to Pollan (2000), the industrial food chain presents significant ethical dilemmas.
Reference List Entry: Pollan, Michael. 2000. The Omnivore's Dilemma: A Natural History of Four Meals. New York: Penguin Press.
Key Distinction within AD: Again, the format for the in-text citations and reference list entries is consistent. Turabian's AD system, like its NB counterpart, offers more specific instructions for integrating these into a student manuscript's overall structure and formatting.
Beyond Citations: Formatting and Manuscript Preparation
This is where the most significant practical differences between Chicago and Turabian emerge for students.
Chicago Manual of Style (CMOS)
- Scope: A comprehensive guide for professional authors, editors, and publishers. It covers grammar, punctuation, style, and citation for works intended for publication (books, journals, professional reports).
- Flexibility: Provides general guidelines for manuscript preparation, often leaving specific aesthetic choices to publishers or individual project requirements. It assumes a professional editorial process will finalize formatting.
- Audience: Primarily professional writers, editors, copyeditors, proofreaders, and publishers.
Turabian's A Manual for Writers
- Scope: Specifically designed for students writing research papers, theses, and dissertations. It adapts Chicago's citation rules and combines them with detailed instructions for preparing academic manuscripts.
- Prescriptiveness: Highly prescriptive regarding overall paper formatting. It offers explicit guidance on:
Title Pages: Detailed layouts for student title pages, copyright pages, and dedication pages. Headings: Specific hierarchical structures for headings and subheadings within a student paper (e.g., Level 1, Level 2, etc., with distinct formatting for each). Margins and Page Numbers: Precise requirements for margins, header/footer placement, and page numbering conventions. Table of Contents/Lists of Figures: Instructions for generating these elements in student papers. * Appendixes and Glossaries: Guidance on including supplementary materials.
- Audience: Primarily students at all levels (high school, undergraduate, graduate) who need to format academic papers according to scholarly standards.
Practical Impact for Students: If your instructor says "use Chicago style," they most likely mean "use Turabian." Unless you are preparing a manuscript for professional publication or have been explicitly directed to use the full CMOS, Turabian will be your go-to resource for formatting your paper correctly. Turabian bridges the gap, providing students with the structure needed to present their research professionally while adhering to Chicago's authoritative citation standards.
Choosing the Right Style: Always Ask!
The golden rule is always to follow your instructor's or publisher's guidelines. If they specify "Chicago style," clarify whether they mean the broader CMOS for publication or the student-oriented Turabian manual for paper formatting. In most academic settings, "Chicago style" for student papers implies Turabian's guidelines.
- Choose Turabian when: You are a student writing a research paper, essay, thesis, or dissertation, and your instructor or institution requires a Chicago-based style. Turabian will give you the most specific guidance on how to format your entire manuscript.
- Choose Chicago (CMOS) when: You are preparing a manuscript for professional publication (e.g., a book, journal article, or scholarly report) and the publisher specifies Chicago style. You might also consult CMOS for more nuanced grammatical or stylistic issues not covered in detail by Turabian.
Similarities to Remember
Despite their differences in scope and audience, Chicago and Turabian share fundamental similarities:
- Common Origin: Both are products of the University of Chicago Press and are built upon the same core principles of clear, consistent scholarly communication.
- Identical Citation Formats: For a given source type within either the Notes-Bibliography or Author-Date system, the actual format of the citation (e.g., how you write a book entry in a bibliography) is virtually the same.
- Emphasis on Accuracy: Both prioritize precise and complete source attribution.
- Logical Structure: Both manuals are well-organized and designed to help writers navigate complex citation and formatting challenges.
Practical Tips for Success
- Consult the Source: Always refer to the most recent edition of the relevant manual. For students, this usually means A Manual for Writers of Research Papers, Theses, and Dissertations by Kate L. Turabian.
- Use Citation Management Tools: Tools like Zotero, Mendeley, or EndNote can help automate the citation process, generating notes, bibliographies, and reference lists in both Chicago and Turabian styles.
- Proofread Meticulously: Even with tools, always proofread your citations and bibliography/reference list carefully. A misplaced comma or period can make a citation incorrect.
- Understand Your Discipline: Familiarize yourself with the common citation practices in your field. While Turabian offers both NB and AD, certain disciplines strongly prefer one over the other.
- Seek Expert Help: If you're struggling with complex formatting requirements or ensuring your paper perfectly adheres to Chicago or Turabian standards, consider professional assistance. Services like Humanize offer expert editing and formatting to ensure your academic work is polished and compliant.
Conclusion
While Chicago and Turabian are often conflated, understanding their specific roles is crucial for academic success. Chicago's Manual of Style is the comprehensive authority for professional publishing, while Turabian's Manual for Writers is its student-centric counterpart, providing specific, detailed guidance for formatting academic papers. Both uphold the highest standards of scholarly citation, but knowing which manual to consult for your particular writing task will save you time, reduce errors, and ensure your work meets the expected academic rigor. Always clarify with your instructor, but generally, students will find Turabian to be the more practical and direct guide for their assignments.
