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.
