Search by ISBN number
Enter an ISBN number to find a book. This tool can also help you validate an ISBN number, fix an incorrect or partial ISBN, or convert between ISBN-10 and ISBN-13.
What's an ISBN number?
The ISBN is a unique serial number for a book. It's usually printed next to the barcode at the back of the book, and on the copyright page.
Each edition of a book has its own ISBN number. For example, hardcover and paperback versions of a book will have different ISBN numbers.
The ISBN can have 10 digits (ISBN-10) or 13 digits (ISBN-13). In an ISBN-10, the last digit can be the letter X. ISBN-10 is an older format, which can be converted to an ISBN-13.
Do all books have an ISBN number?
Most modern books do, but since ISBN numbers have been introduced in the 70s, books older than this period will not have an ISBN number. If they are re-printed nowadays, though, the new edition will be assigned an ISBN number.
Note that some e-books do not have an ISBN number. In theory, each edition of an e-book for each reading platform should have its own ISBN number, but some publishers decide not to attribute ISBN numbers to their e-books.
ISBN groups
Each ISBN-13 number starts with a prefix that indicates which group it belongs to. There are groups for specific countries and languages. For prefixes starting with 978, the part after the dash is a valid prefix for ISBN-10 as well.
