Enjoy all the benefits of a custom ISBN (International Standard Book Number) for each version of your book! While online retailers like Amazon and Barnes & Noble will assign unique identification numbers to your ebooks, having custom ISBNs for these versions makes it easy for you to track and verify your royalties and gives you added peace of mind. Additional ISBNs are also required for print and audio versions of your book. These ISBNs, purchased in your name (and imprint), never expire and can be used for future projects.
Add a ten-pack of custom ISBNs to your package for $295!*
