This volume provides analytical definitions and discussions of the key concepts in archaeology. For each of the more than seventy terms covered, the dictionary provides an examination of the development of the term and an analysis of the key thinkers and writing involved in its development. Each entry concludes with a bibliographical essay designed to cover the original sources of vital importance in the development of the concept---sources such as review articles that provide access to a sizable portion of the literature related to the concept, and a selection of recent publications representative of current directions in research. Additional access to the material covered is provided by an index of concepts and terms and an index of names. This is the first reference dictionary to deal with the concepts in archaeology and, as such, will be useful to scholars and students in the field, as well as libraries supporting research in archaeology.
