My collection includes archival materials on the history of musicology, such as a publicity scrapbook for Gustave Reese’s Music in the Middle Ages (1940), Walter Gerstenberg’s unpublished Habilitationsschrift “Beiträge zur Problemgeschichte der evangelischen Kirchenmusik” (1935), and the papers of Peter Gradenwitz (1910–2001), a German-Israeli musicologist. High-resolution, publication-ready scans are available on request.
I also own a piano-vocal score of an early nineteenth-century Venetian opera by Stefano Pavesi, for which few excerpts survive.
