Citation, Documentation of Sources
Q. Hi—I am a student from Montreal and I am trying to cite an online dictionary and cannot find the proper citation format.
A. Online dictionaries are cited like their print versions, with the addition of a URL or DOI and (if required) access date. If a DOI for the article is available, use that. The facts of publication are often omitted, but entries with bylines may include the name of the author. Well-known online reference works, such as major dictionaries and encyclopedias, are normally cited in notes but not in bibliographies. See CMOS 14.7, 14.8, and 14.232–34 for details and examples.
