Titles

Titles for Smaller Works

Core Elements:

Put quotation marks around, and type smaller works (e.g., articles, chapters, television episodes, songs, poems, etc.) in title case (the first letter of each word is capitalized--except for conjunctions, articles, and prepositions that are not the first words in either the title and/or subtitle). Follow the original capitalization of organizations with their names (e.g., WebMD).

Example:

"Cognition and the Assessment of Interaction Episodes in Jazz Improvisation."
"Building Steam with a Grain of Salt."

Titles for Larger Works

Core Elements:

Italicize and type larger works (e.g., academic journals, magazines, newspapers, books, television shows, etc.) in title case (the first letter of each word is capitalized--except for conjunctions, articles, and prepositions that are not the first words in either the title and/or subtitle). Follow the original capitalization of organizations with their names (e.g., WebMD). Websites, however, are not italicized.

Examples:

Mo' Meta Blues: The World According to Questlove
Last Night the Moon Came Dropping Its Clothes in the Street
Resident Advisor
HuffPost

Publication Dates

Date Is Available

Core Elements:

Year [...] Month Day, Year
Year appears after authors in the citation. The month and day often do not appear until much later in the citation, with the year repeated afterwards. Journals and books, include year only.

Example:

Sandoval, Lapacazo, and Art Shrian. 2016. "Roxane Gay Becomes First Black Woman to Write for Marvel." New York Amsterdam News, September 8, 2016. https://libproxy.howardcc.edu/login?url=https://search.ebscohost.com/login.aspx?direct=true&db=a9h&AN=118092509&site=ehost-live.

No Date

Core Elements:

n.d.
Use n.d. (for "no date") in place of the year. If it is a website or a database resource with no publication or revision date (copyright dates are not considered relevant for resources accessed online with Chicago), then include an access date before the URL.

Example:

The History Teaching Institute. n.d. "Loyalists and Loyalism in the American Revolution." The History Teaching Institute @ The Ohio State University. Accessed November 8, 2017. https://hti.osu.edu/history-lesson-plans/united-states-history/loyalists.

Page Numbers

Core Elements:

Chicago does not use p. or pp. for footnote citations. Simply list the page numbers--however, when supplying page ranges, forgo the larger repeated digits (e.g., 150-60 instead of 150-160).

Examples:

78-83
84-9
1002-7

Web Addresses (URLs) and Digital Object Identifiers (DOIs)
