How It Works

The Book Finder tool connects to the OpenLibrary API, a free and open database of books. By providing a valid ISBN, you can retrieve publicly available information about a specific book edition.

  1. Enter an ISBN: Type or paste a 10 or 13-digit ISBN into the input field.
  2. Click "Find Book": The tool will query the OpenLibrary API for that specific ISBN.
  3. View Details: If the book is found in the database, its cover image, title, author, and publication year will be displayed.

This tool is perfect for cataloging your personal library, checking details of a book you've seen, or simply for curiosity. All data is fetched on-demand and is not stored by our application.
