MLA (Modern Language Association) is a formatting style that allows academic writers to structure their texts according to certain guidelines that stipulate both the format and the citation style that their texts should follow. It is mostly used in language and literature studies, although recently it is widely used also in all fields of the humanities.
When referencing an author´s work, and when the name of the author is already mentioned in the sentence preceding the reference, one should only include, in parenthesis, the page(s) referenced.
Since you've already mentioned who the author is, you don't have to mention him again. The book title would only be added if you're using multiple sources from the same author. If only one, then the page number only.
