Hi, Does anyone know the best way to get all the ISBn numbers of books listed on amazon.com by category & subcategory wise? I need this for a project i'm working on related to books. I'd be willing to a Pay someone, if they can provide the data ready made
You may be better off posting this to the buy & sell forums. I may have something for you though, here's a book ISBN database with 3,966 layered categories and 79,742 subjects and 1.3 million books. Amazon.com is a pretty huge database, with potentially hundreds of millions of books. Getting the ISBN of them all would cost a lot. They have a handy web service in place for affiliate marketers, you can query for a certain type of books with it. But as I said, getting them all costs significant amount of time.
