Most of the books I buy I read and keep them. My book shelf is every full at the moment. However there are a few books (one that I have bought doubles because of a lot sale or ones I just did not like) I will trade off or sell them on ebay. It is really hard for me to let go of my books for some reason...

I tend to keep all of the books I get, I'm a bit of a horde-er.

But that EREADER sounds really cool. I'll have to look into that, it would sure save some space.
