welcome discoveries Scholastic's Voyages of Discovery series, distinctive for its brilliantly colored, innovative design and interactive format, adds two new eye-catching volumes. The History of Making Books tells the story of the written word, from hieroglyphics to electronic libraries. Vivid photographic illustrations and film overlays help exemplify the processes of illuminating a manuscript or printing by color separation, and a heavy gun-metal gray page with raised type represents a printer's box full of metal characters. A page of stickers enables readers to pretend to set movable type or paste in endpapers. Similarly exciting embellishments jazz up geology and geography discussions in Our Changing Planet.
