Buying ISBNs? Learn why owning your Bowker block is essential, and how to configure custom publisher imprints.

Senior Managing Editor

"An ISBN is your book’s retail fingerprint. Owning your ISBN blocks through Bowker establishes you as the official publisher of record."

Core Key Takeaways

  • The Danger of Free Publisher ISBNs
  • Registering Imprint Details in Bowker
  • Mapping ISBNs to Formatting Editions

1. The Danger of Free Publisher ISBNs

Free ISBNs offered by KDP or Draft2Digital list them as the publisher of record, blocking you from selling directly to physical stores.

  • Buy ISBN blocks (packs of 10 or 100) directly from Bowker (MyIdentifiers).
  • Configure your imprint name to match your publishing brand.
  • Set metadata details before distributing books to retailers.

2. Registering Imprint Details in Bowker

Register your publishing imprint name in Bowker. Once set, this name will display across all online retail sites.

3. Mapping ISBNs to Formatting Editions

Each format of your book (eBook, paperback, hardcover, audiobook) needs a unique ISBN to keep retail tracking organized.

The Takeaway

Custom metadata ownership secures publishing rights. Golden Ivory Publishing manages ISBN blocks and catalog registries for authors.
