ISBNLookup.org

ISBNLookup.org finds book information from an ISBN number. The user enters a 10 or 13 digit ISBN, and the tool queries bibliographic databases, library catalogs and retailer sources to gather details such as the title, author, publisher, page count and cover image.

The site also offers AI-generated overviews that summarize a book and offer an analysis of it. A barcode scanner lets users point a phone or other device camera at a book barcode for a lookup without typing the number.

The site explains ISBN basics on its page, including where to find the number on a book and how ISBN-10 differs from ISBN-13. It converts between the two formats automatically.
