Web Service to get Books details

Is there any publicly available web service where I could get book details. Given a开发者_C百科 book title it should return the ISBN number, author, year of publication etc.

Amazon has data services that allow you to search for books.

I think they are still free to use. You need to register, and also the user agreement says you may use these APIs only if you drive commerce traffic back to Amazon's site.
