Mastering Chicago style footnotes transforms how you document research, moving beyond simple source listing to provide a layer of scholarly context and precision. This system, favored heavily in history and the humanities, uses superscript numbers in the text that correspond to detailed citations at the bottom of each page. Unlike parenthetical styles, footnotes allow your main argument to flow uninterrupted while housing complex source information discreetly.
Understanding the Two Chicago Systems
The Chicago Manual of Style presents two distinct documentation systems, and choosing the right one is the foundational step. The Notes and Bibliography system is the classic format for footnotes, utilizing a superscript number and a corresponding detailed note. The Author-Date system, more common in the sciences, uses parenthetical in-text citations and a reference list, which typically does not utilize traditional page footnotes. For the purpose of this guide, we focus exclusively on the Notes and Bibliography method, which defines the traditional Chicago footnote.
Basic Formatting Rules
Chicago style footnotes follow specific formatting rules that ensure consistency and readability. Notes should be single-spaced with a blank line separating each new note. The first line of the note is indented half an inch, similar to a standard paragraph, while subsequent lines remain flush with the left margin. Footnotes appear at the bottom of the page where the citation is made, maintaining a clear visual connection to the relevant text. Font size and type should match the main text of the document, usually 12-point Times New Roman or a similar serif font.
First Note Example
The first time you cite a source, the note must be comprehensive, including all relevant publication details. For a book, this typically means the author's full name, the title in italics, place of publication, publisher name, and the year of publication. Page numbers for the specific reference should always be included at the end of the note. This thoroughness allows a reader to locate the exact source without consulting the bibliography immediately.
Subsequent Citations Simplified
After the full citation appears in the first note for a particular source, you can simplify all following references to the same work. Shortened notes use the author's last name, a shortened form of the title if necessary, and the specific page number. This maintains clarity without repeating the entire publication chain. For instance, a subsequent note for a book might look like this: Chicago Manual of Style , 154.
Shortened Note Example
Efficient writing relies on the ability to reference sources quickly once the initial groundwork is laid. Using the author's name and a key page number provides immediate context for the reader. This method applies to both direct quotes and paraphrased ideas drawn from the same source as the original full citation.
Handling Common Source Types
Applying the Chicago system to various materials requires slight adjustments to the core format. Journal articles demand the article title in quotation marks and the journal title in italics. Websites necessitate the URL and the date you accessed the material. When citing a source within another source, known as an indirect citation, you should credit the original work whenever possible, using "qtd. in" to indicate you are quoting a source quoted in another. The table below outlines the basic structure for common sources.
