Functional Analysis has become firmly established as a methodology of archaeological research and is seen to play a crucial role in the disciplinary advance of archaeology. This present volume developed from the 1st Conference on Functional Analysis in Spain and Portugal, held in Barcelona at the end of 2001. The 29 papers focus on various aspects of prehistoric activity in the Iberian Peninsular. The first section of the book is dedicated to theory and methodology; the second part concentrates on new methodological advances, and the third concentrates on specific hunter-gatherer sites from different archaeological periods.
