The focus of Richard Zgusta's The Peoples of Northeast Asia through Time is the formation of indigenous and cultural groups of coastal northeast Asia, including the Ainu, the "Paleoasiatic" peoples, and the Asiatic Eskimo. Most chapters begin with a summary of each culture at the beginning of the colonial era, which is followed by an interdisciplinary reconstruction of prehistoric cultures that have direct ancestor-descendant relationships with the modern ones. An additional chapter presents a comparative discussion of the ethnographic data, including subsistence patterns, material culture, social organization, and religious beliefs, from a diachronic viewpoint. Each chapter includes maps and extensive references.
