Encyclopedias are always referenced the same way both in text as well as in a works cited page. This means that encyclopedias are cited in the exact same manner to in a bibliography or a works cited page. In order to cite an encyclopedia in text in MLA format, cite the piece referenced, the encyclopedia used, followed by the edition and date published. For instance :’ Magna Carta’, The New Encyclopedia Britannica. 15th ed. 1998.
