Do you keep all the books you ever buy? Just the ones you love? Just collectibles? What do you do with the ones you don’t want to keep?

I do not keep very many of my books because I read so many. I keep classic and ones that I love and know I will read again. I will keep a series that I really enjoy but that is about it. I do not count my history books in that general area because they used to be for work 🙂 but I keep those as well.
