'...this work has a lot to recommend it. It benefits from clear organization, a generally explicit exposition of approach, data and results, and a cogent synopsis of relevant environmental data. ...Blades' study has provided a useful theoretical framework through which to consider Paleolithic cultural groups, as well as data that can be employed for further testing. This is a welcome addition to the ever-expanding literature in the Western European Upper Paleolithic.' Lithic Technology, 27:I 'Works on stone tools are often dry and rather uninspiring in the face of such enormous expectations, but by placing the lithics into a broader ladnscape and ecological context, this work makes a better read than most.' Antiquity, 75:289
