Bach-Werke-Verzeichnis

In 1950, Wolfgang Schmieder published a thematic catalogue of Bach's compositions called the Bach-Werke-Verzeichnis (Bach Works Catalogue). Schmieder largely followed the Bach-Gesellschaft-Ausgabe, a comprehensive edition of the composer's works that was produced between 1850 and 1900. The first edition of the catalogue listed 1,080 surviving compositions indisputably composed by Bach.
