I have been looking for an online or print catalogue of Byzantine Greek ecclesiastical manuscripts in Venice libraries. I am trying to track down a Greek gospel dated 1064 that was No. CLXVI in the Nanni Library in Venice before that library's holdings were distributed to other institutions. Can anyone point me to a post-WWII catalogue of mss. at the Hellenic Institute, the Biblioteca Marciana in Venice, or other libraries in Venice? I have not found this ms. in the B. Marciana's online catalogue, but perhaps that's because I don't know its modern shelf number.
