Collaboration by the universities of Sheffield and Kalmar and Stockholm in Sweden led to two conferences being held. The second, held at Sheffield in 2006, sought collaboration and the sharing of information on archaeological data and theoretical thought on material culture diversity in the third millennium BC. Nineteen papers are presented in this volume arranged under three headings: material culture diversity in the Baltic; British Beaker burials and the Beaker People Project; Stonehenge and the Stonehenge Riverside Project. General overviews and wide-ranging discussions are joined by results from particular field orr laboratory projects.
