Gr 3-6-These four titles focus on the animal kingdom in a straightforward manner. All have vibrant photographs, text boxes, and "Did You Know?" sections that provide unusual and high-interest facts. Each title contains several chapters on individual animals, with opening chapters that offer a more general overview. Mollusks is the least successful as it does not provide a clear initial statement of similarities and differences among the two groups considered. Comparable to Bobbie Kalman's "The Science of Living Things" series (Crabtree), these offerings explore their subjects in greater depth than Lynn Stone's "Animal Kingdom Discovery Library" series (Rourke, 1997).-Gloria Koster, West School, New Canaan, CT Copyright 2005 Reed Business Information.
