Dear sapientes, I have a friend working on Giles of Rome's 'De praedestinatione et praescientia, paradiso et inferno' (ed. Rome 1555). She would like to do a new edition of the work, and has traced manuscripts in Paris, Munich, Laon, Vatican, etc. through catalogues, but is a bit mystified as to which catalogues to use for the United States. I was one shown the system as an undergraduate, but my memory fails me. Could anyone point the way to which catalogues, etc., are appropriate (for institutional or private collections)? Thanks in advance for your help. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
