Does anyone know of a good resource site that has a (reasonably) comprehensive archive of non-fiction books? Something like what
imdb is for movies.
Currently, I am using amazon.com, but, while it is useful, it is far from ideal.
Preferably, I would like to be able to access reviews of books, written by people who know what they are talking about.
Also an area to discuss the books would be nice also (not a discussion area per book like imdb, obviously enough, but finely categorised areas would be useful).
