Dear friends, I would plea for the new system (of course, I have to). We will present the reconstructed version of the c minor symphony no. 3 on November 24 (Mals) and 25 (Innsbruck). Since there is no indication for the dating of the three movement fragment in C major, which is for piano 4hands and appears to be a sketch only, I would suggest to exclude this from the canon. Meanwhile, I have published the announced complete worklist, which will be available online soon. And we have already decided to adopt the new system for our November concert and the forthcoming CD release. The RISM data is old and, in this case, outdated.
