Almost 40 years ago, Dr. A. S. W. Rosenbach, one of America's greatest bibliophiles, and himself an avid collector of children's books, wrote: "Children's books have such a many-sided appeal that they are strangely satisfying to the collector. Not only do they have as much scholarly and bibliographic interest as books in other fields, but more than any class of literature they reflect the minds of the generation that produced them. Hence no better guide to the history and development of any country can be found than its juvenile literatune."
