[quote="bloke"]' nearly always a better idea (if one exists) to find a Breitkopf & Härtel edition of any given piece. The Kalmus editions also tend to clumsily typeset (shifting to the left or right loudness markings, crescendi/diminuendi, etc...)

Kalmus reprints exactly what is on the original plates, so the mistakes will still be in the reprint. Only when an editors name is listed does Edwin F. Kalmus LC. publish a correction of the original edition. Kalmus is correcting the mistakes in the European publications as fast as they can.
