It is often much harder to get rid of books than it is to acquire them. They stick to us in that pact of need and oblivion we make with them, witnesses to a moment in our lives we will never see again. While they are still there, it is a part of us. I have noticed that many people make a note of the day, month, and year that they read a book; they build up a secret calendar. Others, before lending one, write their name on the flyleaf, note whom they lent it to in an address book, and add the date. I have known some book owners who stamp them or slip a card between their pages the way they do in public libraries. Nobody wants to mislay a book. We prefer to lose a ring, a watch, our umbrella, rather than a book whose pages we will never read again, but which retains, just in the sound of its title, a remote and perhaps long-lost emotion.
