The Cat in the Hat Learning Library is a new series of super simple non-fiction books, written expressly for beginning readers. An offshoot of the phenomenally successful Beginner Book Series (which has combined sales of over 53 million copies sold since 1957), each hardcover features the Cat and cast from the original Cat in the Hat and The Cat in the Hat Comes Back — Sally, Dick, Thing One, Thing Two, Mother, Norval, Little Cats A through Z — in a funny, irreverent, rhyming, fact-filled (but scientifically sound) introduction to such concepts as birds, animals, dinosaurs, space, weather, and ocean life. Developed in cooperation with a leading children's reading authority, and thoroughly vetted by experts for accuracy, the books are classically Seussian in sound, spirit, and look. Each book includes a simple glossary and index.
