Chasing Hawk

I don't write or mar my books in anyway. I try not to bend the covers of my paperbacks too much either.
In the strategy books I own for video games I play I use those sticky tabs to mark things I want to look up while playing said video game. Same goes for "instructional books" for sewing, quilting and other hobbies I have. The automotive manuals we have for our trucks are not marked up slips of paper are used to make notes and left where needed in the manuals. Although those manuals do get a bit dirty while working on the trucks.
