In the body of your text, after the quotation, in parentheses, put the last name of the author, followed by a comma, and then the page number where the text appears. Ex. (Melville, 278). In your bibliography, cite the book by all the rules of MLA style (check manual for all the nuances) as follows: Melville, Herman, Moby Dick, New York, Doubleday 1978. There are many variations, but this is the basic structure. If you quote more than one book by the same author, your in-text reference must include the title of the book also: (Melville, Bartleby the Scrivener, 143). This system doesn't interrupt the flow of the reading, but supplies sufficient information to identify your source.
