Extraits p. 638-640 (...) is a noteworthy collection of articles that addresses the various analytical methods as well as the history and archaelogy of the stydy of ground stone implements. (...) Some overlap exists between the different articles across the sections, but this is to be expected in the study of ground stone implements, where multi-disciplinary approaches are important. Each article has high-quality graphics and photographs and an extensive bibliography. A very useful French-English lexicon of geological and technical terms related to the study of ground stone tools makes the French papers more accessible, as least to this reader. (...) Most importantly, the research presented at this round table demonstrates that no one can disregard the role of ground stone implements and their importance in the day-to-day life of ancient cultures.
