b. 15-18

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In A (→FC,FE) there is no  lowering f to f in the 3rd L.H. figure of each of these bars. Interestingly enough, Chopin was convinced that there was no need for an accidental here, since he crossed it out the first time (in b. 15). All naturals were added in GE and EE

composition: Op. 2, Variations, complete

The  restoring b1 in the 2nd half of the bar is absent in all sources. It must be Chopin's mistake, one of his most frequent errors.

In A, CDP, FE, and EE1, there is no  raising d2 to d2. This patent oversight was corrected in GE and EE2 (→EE3). AI also includes the correct notation.

composition: Op. 26 No 1, Polonaise in C♯ minor

3 staccato dots in GE2 (→GE3)

2 staccato dots in A

3 staccato dot in FE (→EE)

No dots in GE1

..

The absence of the staccato dot in A for G1 in the L.H. in bar 16 is to be considered to be Chopin's oversight - the dots are present in similar bars 14 and 18. Chopin did not correct the mistake in the proofreading of FE, moreover, in FE (→EE) the engravers overlooked also a dot in bar 19, which in A is written in an abbreviated manner, with a repetition sign of the previous bar. In GE1 the sign was placed only in bar 14. A revision was performed respectively in GE2 (→GE3), validly adding dots in all analogous places.

composition: Op. 35, Sonata in B♭ minor, Mvt III

..

In [A] (→GC,FE) Chopin overlooked the bass clef. The sign was added in GE and EE. Similarly in all repetitions of this place.
