"An International Standard Book Number (ISBN) is a unique identifier assigned to every version of a book. To publish professionally, you should purchase your own ISBNs from Bowker (the official US agency) rather than using free retailer codes."

Core Key Takeaways

  • Registering Your Custom Imprint Name
  • Mapping Book Metadata on Bowker Link
  • Registering Barcodes for Physical Book Retailing

1. Registering Your Custom Imprint Name

When buying ISBNs on MyIdentifiers (Bowker), you must register a custom publishing imprint. This Imprint Name appears in bookstore databases as the official publisher.

  • Purchase ISBNs in packs of 10 or 100 to save on formatting budgets.
  • Register your imprint name exactly to match bookstore structures.
  • Assign a separate unique ISBN to print, ebook, and audiobook formats.

2. Mapping Book Metadata on Bowker Link

Once an ISBN is assigned, upload your book cover, title, description, pricing structure, and target categories to Bowker's database to publish details to global databases.

3. Registering Barcodes for Physical Book Retailing

Retailers scan barcodes containing the ISBN and pricing structure. Bowker generates compliant high-resolution barcode layouts for your cover wrap files.

The Takeaway

Owning your ISBN registers you as a serious independent publisher. Golden Ivory Publishing guides authors through Bowker registry setups.
