What do you do with books you no longer want? I've got too many books and am trying to narrow down my collection. I'm going to look through them and see if any would be worth selling on ebay but most of them I would rather donate somewhere than sell. Any ideas where to?

I'm in the same boat. I'd rather be using my Kindle more than have a big collection of books taking up space. If I'm not going to read it more than once especially. Maybe try libraries or schools?
