I recently became acquainted with the work of the above-mentioned composer though the recordings to be found on the Piano Society site ass well as some on You Tube. I have managed to acquire a certain number of his piano works but I cannot find his 7 Preludes op 40. These have been recorded on this site by David April and there are two or three recordings to be found on You Tube, all by different pianists. There seems to be no printed version available. I have contacted the Netherlands Music Institute, but they do not have a printed copy, but only the manuscript, which they can supply against payment. The IMSLP does list a number of works by Bortkiewicz, all of them old editions, dating from the 30s and 40s. There is a scan of these Preludes, but, as these are not in the public domain in the EU, access to them has been blocked, I suppose to protect the author (dead) and his heirs (which are dead too, for all I know), which is all very well, except that in this case it is not possible to purchase the printed score! I might end up buying a copy of the manuscript, but before I do that, does anyone know how I could obtain a legal copy of the printed score? How did David April get one, does anyone know?
