Gr 5-8-The mighty Mississippi nearly cuts the contiguous United States in two. The Rhine is not the longest river in Europe, but it is the busiest. The stories of these two rivers are aptly told in these series offerings. Chapters include general history, geology, ecology, and commerce and industry along the rivers. Each title offers one map that clearly shows the paths each river takes. Black-and-white illustrations and well-captioned photographs and gray sidebars complement, without crowding, the texts. Although the books have identical forewords, they are not cookie-cutter offerings. These books are for an older audience than the "Great Rivers of the World" series (World Almanac). Although rather drab in appearance, Currie's and Kallen's efforts are good for serious report writers looking for solid information.-Anne Chapman Callaghan, Racine Public Library, WI Copyright 2003 Reed Business Information.
