In the tradition of Dorling Kindersley's award-winning Eyewitness Guides, the Eyewitness Visual Dictionaries turn learning into an art form. The fresh "visual" approach to words and their meaning is designed to appeal to all ages and interests. full-color "exploded view" photographs reveal objects in amazing detail, while the informative text and thorough labeling help readers understand the way parts relate to one another as well as how an object functions. Subjects vary widely - from sailboats, to umbrellas, to the inner workings of the human heart. Taken together, the Eyewitness Visual Dictionaries serve as a valuable reference tool for home, school and library.
