Since most publishers need more than one ISBN for each new release, we have decided to offer a block of ISBNs for a single title. Remember, each version of a published work requires a unique ISBN number.
A block can be used to publish a print, Kindle, ePub (Nook), and an iTunes version, all with unique ISBNs. This includes unique barcodes for inclusion on the back cover. Each version will be added to the Books in Print database, and will receive free advertising on our advertising channels.
A block of four ISBNs for a single title is $20.00, and members can add up to four additional ISBNs for that single title for $5.00 each.
A block of three ISBNs for a single title is $16.50, and members may add up to three additional ISBNs for that single title for $6 each.
Single ISBNs are still $9 each.
