1. It would probably be better to have the Parma Mss. sent to Venice, since both the Venice and Parma Mss. being in oblong format and since the Parma Ms. is important chiefly as a text revision of the Venice set, they can be photographed together, two volumes at a time, with parallel texts of the same sonatas on the same exposure. I have already explained this to the Venetian photographer, Fiorentini, who made for me some satisfactory samples in microfilm. As I said in my cable, he will do quantity work for seventy five centesimi an exposure and has free access to anything in the Biblioteca San Marco, without being obliged to supply a second copy for the library. (This was confirmed to me by the director himself.) … The director of the Bibliotheca Palatina in Parma offered to have the volumes sent to Venice for the purposes of my own study, but it was then too late for me to take advantage of the offer. Although the Venice and Parma Mss. do not entirely coincide either in order or contents, the parallel passages can easily be traced by the photographer through the use of the comparative table given in Gerstenberg's book Die Klavier-Compositionen Domenico Scarlattis. This I also explained to Fiorentini.
