We have WAY too many books. I have no idea how we ended up with so many. I would like to donate a bunch of them but how do I know which ones to pick? We have some for older kids, younger kids, etc. So far, I have a pile of books I don't like. I recently donated 2 Pooh books I couldn't stand. That pile does not include books she likes (I suffer through books I hate if she really likes them...)

How do you decide what books to get rid of?
