Understanding connectivity is a key to understanding decision making. Social network analysis offers formalized ways of describing and thus comparing attributes of actors related to each other in networks. Using quantitative spatial data, social network analysis promises deeper insights into how social positions are achieved and developed, as mirrored in the ancient flows of materials. The volume collects contributions of an international conference on network analysis in archaeology, held in 2015 at the University of Cologne as part of the DFG Research Training Group 1878 ‘Archaeology of Pre-Modern Economies’. Authors are Geoffrey E. Braswell, Gary M. Feinman, Mark Golitko, Jessica L. Munson, Linda M. Nicholas, and Allen Wilhite.
