Whats an ISBN?
An International Standard Book Number is a 10-digit or 13-digit number used to give every book its own identification label. You may be unsure of a book’s full title, author, or year published, but if you know its ISBN, you can be sure you’ve got the right book. If you cannot locate your book’s ISBN on the outside of the book, open the front cover and look on the page immediately following the title page. This should be the copyright page and will include information about the copyright date, the author and publisher. The ISBN should be in the middle or at the bottom of that page.
