I pretty much do this somewhat with paperbackswap.com It is a great book swap site based on ISBN - btw - they are updating the ISBN fields to hold more numbers - a lot of the book sites might be wonkers for a while until it is over.

Anyway, I love paperbackswap - not only can I connect with other people into the same stuff as I am - I get books free. All I have to do is give one for one away and pay the shipping cost. It equals out to about 1.76 per book.

It has a place for your library where you can post all your books, and your reviews, and your 'to be read' list of books you've got but have not read yet.

Anyway, I'm not affiliated with them - just use the site and love it. Any book lover might so I thought I'd mention it.

(I checked this out - it costs if you have over 200 books. That's not as many as it might sound if you are a bibliophile. I've got about 900 JUST up for sale or to give away. That's not even including my current 'keep' books.)
