Issues : Omission of current key accidentals

b. 561

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE, there is no  raising c3 to c​​​​​​​3. The patent mistake was corrected in GE and EE. In turn, the missing  restoring g3, necessary in this context, even as a cautionary accidental, was added only in GE.

b. 636

composition: Op. 11, Concerto in E minor, Mvt I

..

A sharp raising c2 to c​​​​​​​2 appears in FE (→GE1GE2,→EE1EE2) only just before the 4th quaver of the bottom voice. Chopin would write an accidental too late on a few occasions (e.g. in the Etude in F Major, Op. 10 No. 8, bar 43). An accidental at the beginning of the bar was added in EE3 and GE3, yet it was only GE3 that removed the  in the middle of the bar, unnecessary in this situation.

b. 649-650

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE, there are no sharps raising g2 to g2 (in both bars) and c3 to c​​​​​​​3 (in bar 649). In GE1 (→GE2), the first two were added; the notation in EE and GE3 is fully correct.
