What's an ISBN?

An ISBN is a unique number specific to a particular title and edition of a book and the best way to identify your book. You can find the ISBN on the copyright page and back cover of your book. Do not use an ISBN that is printed on a sticker on your book – defer to the copyright page and make sure you are choosing the correct version of the book.
