BWV

Alternative classifications

BWV numbers were assigned to 1,126 compositions in the 20th century, and more have been added to the catalogue in the 21st century. The Annex of the BWV (BWV Anh.) lists over 200 lost, doubtful and spurious compositions. Occasionally works that have no BWV number can be identified by their BC number, e.g. BC C 8 for "Der Gerechte kömmt um", an arrangement attributed to Bach which was unmentioned in 20th-century editions of the BWV.
