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?
So they either stay on my Kindle app on my iPad or if I eBorrowed the book from the library, they go back. I used to have paper books and other than the ones I kept for sentimental reasons or because they would not look as good as an eBook (art books) or ones I couldn't buy in this country as an eBook (German books from Germany), I donated the rest to a local library. I figured they could inspire others at the library - whether on the shelf or at a book sale.
I can't talk for others but I felt my paper books in my library were essentially a mausoleum of ideas. I felt that those books were better freed and in the world. Just my own opinion and not applicable to anyone but to me.
