This section features the Autographs and Rare Documents Collection of Rai OSN: 152 documents, including letters, music scores, engravings, daguerreotypes, which make up a corpus of very relevant sources from the historical-philological standpoint. The research group, starting from the study Alberto Basso published in 1962 (Autografi di musicisti e stampati di interesse musicale, Italgrafica, Torino), has reorganised, analysed, digitised and catalogued each and every single bibliographic unit, making 67 previously unknown documents available to the scientific community.
