Publishers with many titles can request a block of ISBNs. The portal lets you apply for multiple ISBNs in one request. Larger blocks may need proof of publishing activity. Use blocks to keep numbering consistent across series.
Metadata and cover requirements
Enter accurate metadata. Use the exact author name and edition. The title page and verso (copyright) page should carry the publisher's details and the ISBN. Printing the price is a trade convention set by retailers, not an ISBN requirement.
Common pitfalls
- Don’t use a printer or seller’s name as publisher unless they are the publisher.
- Avoid duplicate entries for the same title. Check title and author carefully.
- Upload clear scans of the title page and publisher page.
- Keep consistent ISBN placeholder format on your cover file.
ISBN and Barcode
ISBN is a number. Since the move to 13 digits in 2007, the ISBN is itself the Bookland EAN-13. The same 13 digits are simply encoded into an EAN-13 barcode symbol. The ISBN must also appear in human-readable form, prefixed with the letters 'ISBN', above the barcode on the back cover.
Rights, editions and reprints
Each format and edition needs its own ISBN. If you change the binding, or move from paperback to hardback, assign a new ISBN. Minor corrections do not always need a new ISBN, but new editions do.
