I turned to the books. The section I was standing in was full of children's books. I drifted along, noticing textbooks mingled with pictures books, and an assortment of books you don't usually see in libraries: family Bibles, photo albums, telephone books. Some of the books had catalog numbers on their spines, some didn't. The books weren't arranged by subject, and some of the numbers seemed to belong to different systems. In fact, the books seemed to belong to many different libraries.
