On a similar note, people are way too precious about their dead-tree books. Feel free to chuck them in bags, make notes in the margins, fold pages, underline, and strike through text in them. It's yours. Make it yours! Your scribblings don't detract from what's in there – they elevate it to something unique.
(This is particularly true if it's a book that's still in print, or was in large enough print runs it's easy to buy another second-hand copy when the one you have falls apart. It's still somewhat true even when that's not the case.)
