I was working on indexing my bookcollection this weekend and while looking at the stacks of books I had lying around I decided I wasn’t, under any circumstance, going to enter all the data from those books (ISBN/ISBN13, Author, Title, Summary, Publisher, etc) by hand.
So after googling around a bit I found ISBNDB.com which is, in essence, google for books. They crawl the internet searching for bookrelated data and then indexing it themselves. They really do store alot of information about books and cross index that so you can technically search for the categories an author fits in and then search other authors that fit in those same categories.
The best part is though, that they publish all this information through a free webservice. So I wrote a wrapper for this webservice that exposes all the methods and results used that can be used in PHP. If you are interested you can download it here. Documentation here.
