Since his death in 1935, Heinrich Schenker's influence on music theory has steadily increased. This indexed guide to an archive of Schenker's manuscripts is augmented by the Nachlass of his pupil Jonas and his close friend Violin. The catalog describes each manuscript and provides access to Schenker's critical works, his annotated scores and performance comments, his correspondence with Furtw�ngler, Schoenberg, and others, and his diaries (1896-1935). The Jonas collection is at the University of California, Riverside.

Accompanying CD-ROM, with titles Heinrich Schenker : Leben - Schüler - Wirkung = Heinrich Schenker : Life - pupils - influence, is a virtual version of an exhibition presented in 2003 at the Universität für Musik und Darstellende Kunst Wien with title: Rebell und Visionär : Heinrich Schenker in Wien.
