PreSchool-Grade 1–Zoos are great places for children to view animals they might never get a chance to see otherwise. But are they beneficial to the animals? While that might be a philosophical debate beyond the scope of this series for emerging readers, some of these books venture into those waters–and, in the case of Lions, even imply that they should be in zoos for their own good. Other books, such as the volume about sea lions, simply report about the animals, barely mentioning zoos at all. Information is presented in a random fashion, and each of the titles ends abruptly. The exception is Panda, in which a brief mention of zoos' efforts to protect and increase the panda population rounds off the material, making it the only title that merges the umbrella theme of the series–animals at the zoo–with the subject of the book.
