Book excerpt: Attempts to define behavioral archaeology more comprehensively than is common in order to illustrate its role in the theoretical landscape of contemporary archaeology. To flesh out points of agreement or dissent, the perspectives of the chapters range from those of behavioral archaeology, old and new, to those of historical, selectionist, and postprocessual archaeology. Many of the 15 papers were first presented at a symposium titled "From Airline Trash to Potsherds," held at the 56th annual meeting of the Society for American Archaeology in 1992.
