by Tanner & Pinther. Softbound, 224 pages, 9" x 12". The Indian history of the Great Lakes region of the United States and Canada, and particularly of the Ohio Valley, is so complex that it can be properly clarified only with the visual aid of maps. This  book, in a sequence of thirty-three newly researched maps printed in as many as five colors, graphically displays the movement of Indian communities from 1640 to about 1871, when treaty making between Indian tribes and the United States government came to an end. This text is a truly impressive piece of work. A very important tool for anyone researching American Indian history. Extensive text and period drawings expand the massive data of these maps.
