This book is devoted to the Late Chalcolithic (4th millennium BC) and Early Bronze Age (3rd millennium BC) in Central Anatolia. The present volume is an introduction and consists of two parts. The first part gives an overview of the history of research and chronological concepts. The second part covers the most important sites (at present more than 90), their characteristics, and stratigraphies. This book is the first of a series of comprehensive studies on the Late Chalcolithic and Early Bronze Age of Central Anatolia. The authors have carried out extensive fieldwork and material studies over the last 15 years in cooperation with numerous institutions and colleagues. Since 2005, excavations, prospection work, and surveys have been conducted on a number of sites. In addition, various archaeological finds of this period have been systematically documented and analysed.
