Locating an ISBN

What are ISBNs?

International Standard Book Numbers (ISBNs) are distinctive 10-digit codes used to identify a particular book. These codes and numbers are used to identify the exact item you wish to buy or sell.

How to Identify ISBNs

You will find the ISBN packaging and/or back cover of your book.

Do not include hyphens when entering these numbers. However, if the 10-digit ISBN ends with the letter X, be sure to include it.
