b. 1

composition: Op. 28 No. 16, Prelude in B♭ minor

Staccato in A (→FE)

No mark in FC (→GE) & EE

..

The missing staccato dot is an oversight of the copyist and the engraver of EE.

b. 12-14

composition: Op. 28 No. 16, Prelude in B♭ minor

4 slurs in A (→FE,FCGE) & EE2

1 slur in EE1

..

The missing slur running from the last L.H. quaver in b. 12 and two subsequent ones in b. 13-14 in EE is a patent mistake of the engraver of that edition.
In FC the beginning of the first of those slurs is missing, which – at least theoretically – results in an ambiguity, as far as the presence or range of that slur is concerned, since the next bar is marked in the manuscripts in an abridged manner as a repetition of b. 12. We assume – like GE, based on FC – that the slur at the beginning of b. 13 is to be taken into account, in its full range, which means that it should also encompass the last quaver in b. 12.

b. 28

composition: Op. 28 No. 16, Prelude in B♭ minor

..

EE has a  (cautionary?) before the penultimate semiquaver. In the editors' opinion, it could have been placed there by mistake – it was presumably meant to restore d2 one note before, where it occurs in all the remaining sources, and where it is necessary (the distances between notes indicate that the  restoring d2 was initially omitted, and added only later).

b. 29-30

composition: Op. 28 No. 16, Prelude in B♭ minor

2 slurs in A

No slurs in FC (→GE) & EE
 

Slur in bar 29 in FE

..

In the main text we give the two L.H. slurs beginning in the 2nd half of b. 29 after A. None of the remaining sources reproduced them faultlessly.
