Better Book Category List

I am happy to announce that I have improved the browse by category list available on Compare-Books.com. The old list was, well, very unorganized and the books did not really show up in the right places. I have now included a set of top level categories and a plethora of sub categories in order for users to browse by the specific category that they are looking for. Thanks for everyone's support and suggestions, together we will make this site one of the best for comparing book prices on new and used books and textbooks!
