1. When scanning books, make sure you scan the ISBN barcode, and NOT UPC barcode. For some pocket sized books, the ISBN barcode is on the first page and not at the back of the book.

2. While we have very good coverage of ISBN for most books in the market, our database does not contain every single ISBN in the market. We believe our coverage is close to 99% of all books.
