I would try Daniel Williman, Records of the Papal Rioght of Spoil 1316-1412 (Paris, 1974). I need to check my memory that part of the Avignon library was moved to Rome & is in the Borghese collection. If so, try Anneliese Maier, Codices Burgesiani Bibliothecae Vaticanae (Studi e testi 170; Rome 1952). If you do not have access to these titles, contact me off list & I will look at the volumes. tom izbicki %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
