The easiest way to tell us what books you own, is to search by ISBN. The ISBN is a 10 digit number that identifies the book.

You'll find this on the back of the book. Simply enter the ISBN (no spaces or dashes) into the search box above and hit Search!

You can also search for books by name or by author. Just type in the author's name, the name of the book (or both!) into the search box above and hit Search.

Once you've found a book you own and want to share, just click "I Own This" and we'll add it to your library.

You earn credit by posting books to other people - the more books you add to your library the better the chance that someone else wants one of your books.
