I always thought that someone who uses bookmarks love the idea of a “book” and himself as a “keen reader” not The book and act of reading itself. Books (as a physical object)are printed out for active reading, they should be worn out and covered with hand written notes, they are waiting to be put money, love letters and leaves and flowers in them only to be discovered years later. They don’t mind even to be spilled coffee on, and to be finally forgotten on a train as an anonymous gift for someone else.
