Q: When you’ve read a book, what do you do with it? (Keep it, give it away, donate it, sell it, swap it..?)
I'm mainly an e-reader so there's nothing to do with it except keep it on my Kindle. I have back ups of every book just in case I do delete it off my kindle. I buy very few actual books these days and if I do, it is something that can not be purchased on Kindle like a bonus pack or a guide that doesn't show up well on e-ink screens so those are collectibles in which I would keep.
The books I do have, I keep, even though I may never read them again. Some I keep for sentimental reasons and all I keep for the reason of me liking to collect books :0) I would love to have a huge collection of nothing but beautiful hard covers one day... to go along with a huge library in my future house lol.
