The standard version of this collection is based on the autograph manuscript of 1722 (denoted A1 in the Neue Bach-Ausgabe), to which Bach later made three subsequent series of minor revisions (A2 in probably 1732, A3 probably after 1736, and A4 in probably the 1740s). It is this final version that is given here.

The Neue Bach-Ausgabe also gives the earliest version of the collection (denoted α1). This earlier version is broadly similar to the 1722 autograph manuscript; only the preludes in C major and E minor have significant differences, and are consequently given on these pages.

Some preludes also exist in intermediate versions between α1 and A1: α2 refers to intermediate versions of the preludes in C major (BWV 846/1), C minor (BWV 847/1), D major (BWV 850/1), D minor (BWV 851/1), E major (BWV 854/1), E minor (BWV 855/1) and F major (BWV 856/1), whilst α3 refers to later intermediate versions of the preludes in C minor (BWV 847/1), C-sharp major (BWV 848/1), C-sharp minor (BWV 849/1), E-flat minor (BWV 853/1) and F minor (BWV 857/1). With the exception of the second (α3) intermediate version of the C minor prelude (BWV 847/1), all of these intermediate versions are those in the Notebook for Wilhelm Friedemann Bach.

In BWV^1,2,2a, the main collection is identified as BWV 846–869, with the earlier C major and E minor preludes identified separately as BWV 846a and 855a respectively. In BWV³, the earlier versions are identified as BWV 846.1–869.1 and the standard version as BWV 846.2–869.2.
