The Music Library has just completed a multi-year project to catalog two major collections of rare Italian opera libretti: the Taddei Collection consisting of 4,403 libretti dating from 1600 to 1953, and the Sicilian Libretto Collection containing about 930 libretti dating from 1650 to 1900.
These two collections constitute one of the largest and most important collections of historical opera libretti in the U.S. To browse the collections in OskiCat, type the title search "Taddei libretto collection" or "Sicilian libretto collection."
