Book Not Found

When you scan or search for a book and it’s not found in our database, here’s what you can do.

  • Very new releases — Books released in the last few days may not be in databases yet
  • Self-published books — Some indie or self-published books aren’t in standard book databases
  • Older editions — Very old printings may have outdated or missing ISBNs
  • Regional editions — Some international editions aren’t in US databases
  • Non-book items — Journals, magazines, or other items with barcodes
  • Wrong barcode scanned — Some books have multiple barcodes (price codes, store codes)
  • Damaged barcode — Worn barcodes may scan incorrectly
  • ISBN-10 vs ISBN-13 — Older books may have different ISBN formats

The ISBN is the unique identifier for a book. To find the correct one:

  1. Check the back cover — Look for a 13-digit number starting with 978 or 979
  2. Check inside — The copyright page often lists the ISBN
  3. Look for “ISBN” — The number should be labeled

Tip: If you see two numbers, use the 13-digit one (starting with 978 or 979).

  1. Go to Add BooksSearch
  2. Type the exact title as it appears on the book
  3. Try variations (with/without subtitle, series name)
  1. Search the author’s last name
  2. Browse their books to find the right one
  1. Type the full 13-digit ISBN
  2. If not found, try removing any hyphens
  3. Try the 10-digit ISBN if the book is older

Search for the book on:

  • Amazon or Goodreads — Verify the ISBN and title
  • WorldCat — Find library catalog records

If you can find the book’s ISBN elsewhere, try entering it exactly as shown.

We’re working on a feature to let you add books manually when they can’t be found automatically. Stay tuned!
