Selling/donating/discarding books has made such a positive difference in my life and my storage space. I still have an entire book case of books and my kid's book case is overflowing. But it's only ONE book case in the living room and I have room for board games and photobooks and binders of CDs/DVDs, and we can hang things on the walls. I'm very glad that so many books are being sold without DRM and I can easily store them on an external hard drive as well as have access to them only phone/tablet/computer.
