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. 13

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

..

This bar is written in A (→FC) as a repetition of the preceding one (with the use of /• marks). Similar situations are to be found in b. 11 and 35 and 37.

b. 14

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

in A

No sign in FC (→GE)

Longer  in FE (→EE)

..

The missing  hairpin in FC (→GE) resulted from an oversight of the copyist. In FE (→EE) the mark is longer due to it having been adjusted to the 2nd half of the bar.
