custom book search?
Hey guys, I was on a classified site the other day and I thought they had a pretty cool functionality added to their site. If you posted an add under the "Books" section of their website it gave you the option to add the ISBN number of the book you would like to sell and if you did, it would automatically fill out the title of the listing with the title of the book and would add a thumbnail image of the book as one of the pictures for the listing. It was a very convenient feature and I think could help my site (and others like it allot). My best bet was that they were using one of Google's book search API's http://code.google.com/apis/books/
or something like it to do this on their site. Has anyone ever done anything like this or possibly know how to?
