I sold about 1/3 of my paper books last year. I kept books that are my favorites and that I'd re-read and my Star Trek book collection. Though, I never want to pick up a paper book, I'm always reading ebooks instead. I suppose I should get rid of the paper books I have if I just want to read ebooks, but for some reason I don't want to let go of them. I spent an awful lot of money on them and it would be hard to let them go for next to nothing. Also hard to replace them all with ebooks, because that is expensive. I have replaced a few though, with ebooks and maybe when I buy some more of them on ebook, I'll clear some more out. I can't imagine having no paper books though.
