This important new methodologically-oriented work represents a major step forward in the expanding field of traceological studies...The text is exceptionally well written and documented. Schematic artifacts line drawings ...clearly indicate different use zones on edges and are preceded by a coded use-type key. The 280 x photomicrographs in section III are exceptional as is also the presentation of qualitative and quantitative data. American Antiquity Vaughan's monograph provides a thorough treatment of the high-power microscopic approach to lithic use-wear analysis and will contribute to the resolution of this issue...An excellent introduction to the subject.
