Do you donate your books, try to sell them at your next garage sale, or do you hold on to them on the off chance you might want to reference them again in the future?
What is your reasoning for why you do whatever it is that you do with your books once you've read them?
My wife and I have a ton of books that we have read, intend to read, or have acquired but will likely never read. So I've always got this drive to get rid of old books but there's also something in me that just likes to keep old books around. A library or second hand book store would undoubtedly get more use out of them. So, what's your thoughts about your dusty old tomes?
