The volumes varied somewhat in editorial quality and accuracy; Bach scholar Hans T. David particularly criticized Vol. 31's presentation of
The Musical Offering for numerous incorrect readings, and the
1911 Encyclopædia Britannica calls the edition as a whole "of very unequal merit."
Britannica both lauds the editing of
Wilhelm Rust for the edition and notes a deterioration of standards after his death, including a volume in which "the bass and violin are a bar apart for a whole line" (apparently a reference to sloppy editing). (The Bach-Gesellschaft volume containing the
Goldbergs was one of the first to be published—Vol. 3, which appeared in 1853.) Nevertheless, the Bach-Gesellschaft's volumes were a groundbreaking achievement and contributed greatly to the study and appreciation of Bach's music. They remained the standard edition of Bach's complete works until the publication of the
Neue Bach-Ausgabe by
Bärenreiter and the Deutscher Verlag für Musik (1954–2007). ==References==
