Understanding the difference between MLA and Chicago style is essential for anyone engaged in academic writing. Both systems provide comprehensive rules for formatting papers, citing sources, and creating bibliographies, yet they serve different disciplines and audiences. Choosing the correct style often depends on the subject matter, the specific requirements of an instructor, or the standards of a particular publication.
Core Philosophies and Disciplines
The primary difference between MLA and Chicago begins with their underlying purpose and the fields they dominate. The Modern Language Association (MLA) format is predominantly used in the humanities, focusing on literature, languages, and cultural studies. Its design prioritizes the author and the page number, allowing readers to quickly locate the source in the Works Cited list. Conversely, Chicago style, often associated with history, business, and some social sciences, offers two distinct systems: Notes and Bibliography, which is favored for its flexibility with sources, and Author-Date, which aligns more with the scientific emphasis of APA.
Citation Structure: In-Text References
When examining the difference between MLA and Chicago, the in-text citation style is one of the most immediate contrasts. In MLA, citation is simple and parenthetical, consisting of the author's last name and the page number without punctuation, such as (Smith 45). This method keeps the focus on the text itself. Chicago Notes and Bibliography, however, utilizes superscript numbers in the text that correspond to footnotes or endnotes, where full source details are provided, allowing for extensive commentary. The Author-Date system within Chicago employs parentheses similar to MLA, but includes the year of publication alongside the author's name, like (Smith 2020, 45).
Formatting and Presentation
Beyond citations, the difference between MLA and Chicago extends to overall document formatting. MLA mandates a straightforward setup: double-spaced text, a legible font like Times New Roman size 12, and one-inch margins. The header includes the author's last name and page number in the top right corner. Chicago format is more flexible regarding title pages and spacing; it often allows for a title page and requires specific handling of notes and the bibliography. While both styles require double-spacing throughout the main text, Chicago provides more granular control for block quotes and the presentation of visual materials.
Bibliographic and Reference Details
The structure of the source list highlights another key difference between MLA and Chicago. An MLA Works Cited page lists entries alphabetically by author, with every entry concluding with the medium of publication, usually "Web" or "Print." Titles of works are formatted using quotation marks for articles and italics for books. Chicago Bibliographies in the Notes system follow a similar alphabetical order but employ a different layout, using commas and periods to separate elements, and often including the publication date in a specific sequence. This variation ensures that the information is presented according to the expectations of the academic community.
Handling of Notes
A defining feature of Chicago is its comprehensive note system, which has no direct equivalent in standard MLA formatting. These notes can contain not only bibliographic information but also explanation, expansion, or tangential commentary that would disrupt the flow of the main text. While MLA encourages integrating all source information into the text or using a simple parenthetical reference, Chicago embraces the footnote or endnote as a tool for both citation and intellectual engagement. This makes Chicago particularly valuable for historical research where context is as important as the source itself.
Ultimately, the choice between these styles is a strategic one. Scholars must evaluate the demands of their specific project, considering the expectations of their discipline and the needs of their reader. Whether using the author-page simplicity of MLA or the detailed note-driven approach of Chicago, adherence to the specific guidelines ensures clarity, credibility, and professional presentation.
