Although historical work on the early Middle Ages relies to an enormous extent on the evidence provided by charters and other such documents, the paradigms within which such documents are interpreted have changed relatively slowly and unevenly. The critical turn, the increasing availability of digital tools and corpora for study, and the acceptance among charter specialists that their discipline can inform a wider field all encourage rethinking. From 2006 to 2011 a series of sessions at the Leeds International Medieval Congress addressed this by applying new critiques and technologies to early medieval diplomatic material from all over Europe. This volume collects some of the best of these papers by new and young scholars and adds related work from another session.
