I don't use 'good' books. I only use books I find in used bookstores/antique shops/goodwill. So don't worry. I just feel bad with them laying around lonely. I feel as if I need to make something even more beautiful out of them.
This book here has marks all in it where the previous owner highlighted/underlined a lot of the pages.
Anyway, glad you like it regardless. I know it upsets some people.
