A question born out of my own simple curiousity.
Do you leave your physical mark on your paper books?
Do you dog-ear, highlight, make notes, inscribe your name, or some combination of the above? I have to admit that I don’t do any of those things. I try to keep my books in as pristine condition as possible – it just seems wrong for me to do otherwise. I never even leave them open face down on a table when I’m gone for a few minutes (what I do instead is grab anything that’s handy and use it as a bookmark. The strangest thing I’ve noticed when I came back to a book was our iPad mini happily holding my spot.)
Cookbooks are the one exception to this rule, I’ll make notes off to the side, but not all that often. And it’s not like I’ve never harmed books, it’s just usually unintentional (i.e. dropped in the bathtub).
So, what is it for you? To mark up or not to mark up?
