Does anyone know about any online book communities?

I've been checking out B%26amp;N's online book clubs and so far I like it, but I'm having a hard time figuring out how to post my own question. So I was hoping to find a website that is great for people that like to discuss books or post questions about books. Even something that includes writers would be great. Thanks!Does anyone know about any online book communities?

It's pretty cool. Just put in the ISBNs to make your library. Then you can see how many other people have the books you do, people's opinions on them and discussions about them. It's kinda cool to see who has books in your collection, just to see if they have something that might be good that you don't have.

There are general discussions and groups to join which is what I think you're looking for.



I use it to keep track of my books mostly. I have a whole online list of what I have complete with pictures of the covers and author info, publishing info and lots of cool things.
