This pictorial encyclopedia is a museum in a box for readers 8 and up, packed with 10,000 captioned images of everything from popular cat breeds to precious gems to basic ballet steps, along with timelines, top ten lists, and other fun facts. The ten volumes include two science books (Protons to Planets and Technology to Trains), three on nature (Fossils to Flowers, Fish to Birds, and Horses to Habitats), two culture books (Art to Architecture and Sport to Hobbies), and two on history (Villages to Empires and Exploration to Espionage), plus Geography: Coastlines to Climates. For extra fun, the set includes a light-up voice-changing robot—record your message and play it back in a robot voice.
