When you go to the bookstore, excited to buy a copy of the next greatest book, do you pick up a paperback, its pages opening easily to a random page? or a hardcover, giving you protection against bends and creases?
Do you take notes in your books? Do you fold pages when you find something interesting? Do you bend the spine so it stays open while you read? Or do you try to preserve your books in their original pristine condition? Do you take care to avoid doing the aforementioned things?
