When I've ventured to my local public libraries, except for the children's section, the stacks have been pretty dusty. I haven't borrowed a book from a library myself in at least 5 years. I purchase a lot of books (paper books) -- mostly from Amazon but occasionally from brick and mortar bookstores -- but like to make notes and write questions in the margins or on Post-its and tend to keep them for later reference.
