After 1950, when the Bach-Werke-Verzeichnis was published, it was no longer needed to indicate the Toccata and Fugue in D minor as "Peters Vol. IV, No. 4", as "BGA Volume XV p. 267", as "Novello VI, 1", or without "Dorian", to distinguish it from the Toccata and Fugue with the same key signature. From then on the work has been simply BWV 565, and the other, the so-called "Dorian", has been BWV 538. In 1964, the New Bach Edition included BWV 565 in Series IV, Volume 6, with its critical commentary published in Volume 5 in 1979. Dietrich Kilian, the editor of these volumes, explains in the introduction to Vol. 6 that the New Bach Edition prefers to stay close to authoritative early sources for their score presentations. For BWV 565 that means staying close to the Ringk manuscript. Consequently, the name of the piece was again given in Italian as "Toccata con Fuga", and the piece was again written down in D Dorian (i.e. without at the key). However, more modern conventions were maintained with regard to using the treble clef in the upper stave and using a separate stave for the pedal.
