Operetta Foundation/Friends of Operetta - Archive

Operetta Foundation is a private research institute dedicated to the preservation and promotion of our national and international operetta heritage. Located in Los Angeles since its founding as Operetta Archives in 1997, the Foundation is a not-for-profit corporation that maintains a continually expanding library containing America's largest collection of operetta-related material (books, scores, recordings, sheet music, programs, posters and other ephemera). In addition to providing research and performance materials and producing CDs and DVDs on the Operetta Archives label, the Operetta Foundation produces live events, emphasizing rarely performed and all-but-forgotten music from operetta and early musical comedies.
