When citing a print dictionary in MLA style, do I include a page number?
Yes. Cite an entry in a print dictionary like a section of a larger work. Include the page number in the “Location” element of the MLA style template:
“Content, N. (4).” Merriam-Webster’s Collegiate Dictionary, 11th ed., Merriam-Webster, 2003, p. 269.
To cite an entry in an online dictionary, consider the URL the location:
“Content, N. (1).” Merriam-Webster Unabridged, 2016, unabridged.merriam-webster.com/collegiate/content.
See page 42 of the MLA Handbook for guidelines on when it’s permissible to omit a publisher’s name, as in the above example.
Whether you’ve consulted an entry from a print or an electronic dictionary, you can direct readers to the definition you’re citing in a parenthetical reference:
(“Content,” def. 4.1.b)
