(wikipedia) The Bach-Gesellschaft began publishing Bach's works in 1851 with a volume that started with BWV 1, the cantata Wie schön leuchtet der Morgenstern, BWV 1.[2] It completed publication in 1900 with its forty-sixth volume.[3] However, the edition of The Art of Fugue by Wolfgang Graeser, published in 1926, is sometimes counted as "Volume 47"[4] and was issued as a supplement to the Bach-Gesellschaft publication by Breitkopf & Härtel, publishers of the original series.[5] Additionally, Vol. 45, part 1 includes a revised edition ("Neue berichtige Ausgabe")[6] of the English Suites and French Suites that had previously been published in Vol. 13.
