I've always found old bookstores exciting. Whenever I'm in a city that's new to me, I immedicately look through the telephone directory for BOOKS, USED AND RARE. Book dealers send me their catalogs, and I read them as carefully as I would a letter from an old friend, never knowing what treasure I might find. Sometimes the catalogs contain printed material other than books, such as old photographs, newspapers, pamphlets, postcards, and letters.
