Since its publication in 1955, the Kinsky-Halm as it is known in musical circles, has been an integral part of any scholarly research into Ludwig van Beethoven's works. Yet it serves many other groups and is used by musicians, music scholars, those interested in music, antiquarian booksellers, librarians and authors of programme notes and booklets. The compendium gives information on every composition, including the genesis and performance history, the sources and relevant literature. Numerous musical examples aid the identification of the works.
