The history of archaeology has often, not surprisingly, bene mainly concerned with sites, their excava­tors, and what they found. But of equal importance are the attitudes, beliefs, and assumptions that shape the interpretation of archaeological data. LeBlanc, in Prehistoric Warfare in American Southwest, argues that the long held belief in the essential peacefulness of the prehistoric Anasazi and other South­ western peoples can be shown to be wholly incorrect, and therefore much that has been written about the prehistoric Southwest needs extensive rethinking. Warfare was an important feature of the ancient Southwest, and he presents carefully marshalled evidence, in great details, to uphold his conclusions.
