The Bach-Werke-Verzeichnis (German: [ˈbax ˌvɛʁkə fɐˈtsaɪçnɪs], lit. 'Bach Works Catalogue'; BWV) is a catalogue of compositions by Johann Sebastian Bach. It was first published in 1950, edited by Wolfgang Schmieder. The catalogue's second edition appeared in 1990 and the third edition in 2022.
The catalogue groups compositions by genre. Even within a genre, compositions are not necessarily collated chronologically. In part this reflects that fact that some compositions cannot be dated. However, an approximate or precise date can be assigned to others: for example, BWV 992 was composed many years before BWV 1.
