Papal Reform and Canon Law in the 11th and 12th Centuries [EPUB ebook] 

Published in 1998, these essays focus on Rome and the curia in the 11th and 12th centuries. Several relate to Cardinal Deusdedit and his canonical collection (1087) and to the pontificate of Paschal II (1099-1118). Both personalities and their ideas are presented within the larger setting of contemporary problems, highlighting divergent currents among ecclesiastical reformers at a time of the investiture controversies. A third common theme is formed by discussions of the organization and archival practices of the curia, which were of fundamental importance for the growth and codification of canon law, not to mention papal control of the Church.
