ISBN Lookup Tool

Use the lookup before you trust or publish the ISBN data attached to a book

Look up a book by ISBN-10 or ISBN-13 and confirm the metadata before you reuse it in a listing, barcode, print setup, or distribution workflow.

  • 4.7/5author rating
  • 25k+authors served
  • ISBN-10/13supported formats
  • multi-dblookup sources

How it works

The flow should be simple enough to use quickly and structured enough to produce a useful publishing decision.

Step 1

Enter the ISBN cleanly

Use either ISBN-10 or ISBN-13 and let the validator confirm the format before you rely on the result.

Step 2

Search the book databases

Query multiple public sources quickly so you can confirm whether the number maps to a real title record.

Step 3

Review the returned metadata

Check title, author, publisher, publication date, identifiers, and other fields before reusing them.

Step 4

Use the record in production

Take the confirmed metadata into your barcode, print, listing, or distribution workflow without guessing.

FAQ

ISBN lookup questions before you trust the record

Next step

If the ISBN is confirmed, move the data into the rest of the production workflow cleanly.

The next useful steps are generating the barcode, checking print assumptions, and keeping metadata consistent across channels.

Frequently Asked Questions

Everything you need to know about ISBN numbers, book identification, and lookups

An ISBN (International Standard Book Number) is a unique 10 or 13-digit identifier assigned to published books. ISBN-13s start with 978 or 979, while ISBN-10s are the older 10-digit format used before 2007. Every edition and format of a book has its own unique ISBN.

ISBN-10 is the older format with 10 digits, used before January 2007. ISBN-13 is the current standard with 13 digits, starting with 978 or 979. Both identify the same book, and ISBN-10s can be converted to ISBN-13 by adding 978 and recalculating the check digit.

Check the book's back cover near the barcode, the copyright page (verso), or the book's retail listing on Amazon or bookstores. Ebooks also have ISBNs, typically listed on the copyright page or product details.

Yes, you can search by title or author on sites like Amazon, Google Books, or Open Library. However, ISBN provides the most accurate results since it's a unique identifier for each specific edition.

Yes, each edition and format of a book gets its own ISBN. A paperback, hardcover, and ebook version of the same title each have different ISBNs. Updated editions and reprints with significant changes also receive new ISBNs.

Yes, each format requires its own ISBN. A Kindle ebook, EPUB ebook, paperback, and hardcover of the same book all need separate ISBNs. Note that Amazon's ASINs are different identifiers and not the same as ISBNs.

Add the prefix "978" to the ISBN-10 (dropping the original check digit), then calculate the new check digit using modulo 10. Our tool automatically shows both ISBN-10 and ISBN-13 formats when available in the database.

This tool searches Google Books and Open Library. Most published books including self-published and KDP titles are covered. If a book isn't found in either database, it may be too new or not yet indexed — try searching major retailers like Amazon or the publisher's website.

It depends on your distribution goals. Amazon KDP provides free ASINs, but ISBNs are required for libraries, bookstores, and wide distribution. Owning your own ISBN gives you more control as the official publisher of record.

In the US, ISBNs cost $125 for one, $295 for 10, or $575 for 100 through Bowker (the official US ISBN agency). In the UK, ISBNs cost £89 for one, £164 for 10 through Nielsen. Many self-publishing platforms offer free or discounted ISBNs, though you may not be listed as the publisher.
