This latest edition to the English Episcopal Acta series brings together for the first time edited versions of all the extant charters issued by the bishops of Durham between 1241 and 1283: Nicholas Farnham, Walter Kirkham, Robert Stichill and Robert of Holy Island (the last two, unusually at this date, monastic bishops). The surviving charters provide insights into episcopal administration and estate management in the mid-thirteenth-century diocese. A full introduction considers the lives of these little-studied bishops and the diplomatic of their charters, as well as the unusual structure of the episcopal households here.
