Few pleasures, for the true reader, rival the pleasure of browsing unhurriedly among books: old books, new books, library books, other people's books, one's own books - it does not matter whose or where. Simply to be among books, glancing at one here, reading a page from one over there, enjoying them all as objects to be touched, looked at, even smelt, is a deep satisfaction. And often, very often, while browsing haphazardly, looking for nothing in particular, you pick up a volume that suddenly excites you, and you know that this one of all the others you must read. Those are great moments - and the books we come across like that are often the most memorable.
