Book excerpt: Why do people go to zoos? Is the role of zoos to entertain or to educate? In this provocative book, the authors demonstrate that zoos tell us as much about humans as they do about animals and suggest that while animals may not need zoos, urban societies seem to. A new introduction takes note of dramatic changes in the perceived role of zoos that have occurred since the book's original publication.
