This chapter discusses the origins of the project, the historian's concepts of database entities, ‘humanities computing’, and the new dynamics of collaboration. Prosopography in the sense of biographical compendia of exemplary males, especially office-holders in the service of the state, or church, grew out of those. As other papers in this volume show, an electronic database offers huge potential advantages over the old handwritten card-index methods of assembling a prosopography. This model, of standards adoption and standards building, is no less relevant to projects such as PASE, PBE, and other prosopographical projects. It holds out the realistic prospect, for example, of creating a compendium of all Anglo-Saxon materials, whether historical, literary, linguistic, visual or archaeological.
