|Number of ISBNs||What Are Your Publishing Needs?||Cost|
|Single ISBN||A person who would purchase only one ISBN for $125 is often printing a single version of a single book. Purchasing a single ISBN is not adequate for those who wish to publish multiple versions of the same book (Hardback, Softback, EPUB, MOBI, PDF), or for people who plan to publish more than one book.|
Why a Block of Ten (10) ISBNs is the most
commonly purchased ISBN package.
|100 ISBNs||A block of 100 ISBNs is usually purchased by more prolific self-publishers and small independent publishers. Purchasing a block of 100 ISBNs for $575 is a more cost-effective option if you need more than 2 blocks of 10 ISBNs.|
