This volume contains the acta of three bishops of London: Richard of Ely, William de Ste. Mére-Église, and Eustace of Fauconberg. Both Richard and Eustace saw service as royal treasurer; indeed Richard wrote the handbook on Exchequer practice, the Dialogus de Scaccario. William on the other hand spearheaded the papal campaign against King John during the General Interdict.
