For MLA and citing multiple works by the same author, alphabetise all entries by title in your bibliography, and replace the author name with a 3-em dash (—) in all entries after the first, for example:

Burn, Andrew. The Romans in Britain: An Anthology of Inscriptions : With Translations and a Running Commentary. 2nd ed. Blackwell, 1969.

—, Agricola and Roman Britain. Collier Books, 1962.
