The Modern Language Association (MLA) citation style is the standard style of citation for those writing in the field of English Language and Literature. See the Citation Styles page for up-to-date MLA citation resources and quick guides.
Citing the OED Online
Citing entries in the OED Online is similar to citing print dictionaries. As the OED does not provide entry authors, the title of the entry should be included in the parenthetical citation. If you are referring to one particular definition include the definition number in the parenthetical citation.
The OED Online includes a citation tool, which can be helpful in formatting citations. Look to the right corner of the entry page and click on the "Cite" button. Choose "MLA8" as the style of citation. The citation can then be exported to citation management software (Zotero, EndNote, Refworks).
