There are many ways to cite a book. You could search Wikipedia, eHow, or even Yahoo! Answers to find a way. One way to cite a book is to put in the name of the author first (starting with surname), then the name of the book in italics, and then edition number, city it was published in, name of the publisher, and then the year it was published.
For example: Doe, John. My Book. 1000. IDK City: Acme Publishing, 2010.
