How do you cite a book by that has an author but is told by someone else?

Question

the book is the autobiography of Malcolm X as told by Alex Haley. So how do I cite that?

Thanks!

Answer 1

Is this for a bibliography or for citing a quote?

Edit: I should have paid more attention to the original question. Malcolm-X is the author of the book/quote; the book is _The Autobiography of Malcolm X: As Told to Alex Haley_.  Alex Haley was just the interviewer.
