Austrian Composers

And agreed, thanks!
I wonder if Kurt Richter, in the symphony, might be Kurt Dietmar Richter (b.1931)- there seem to have been several musicians by that name (composers and conductors both), I'm not sure anycase. Hrm.

A few scores can be had legally without charge from the SIbley Library. Not everything there has made its way to IMSLP yet.

nor will everything; they have some scores that they are allowed to display as a (real) library under various US copyright law exemptions that don't apply to IMSLP (I hope that my communications on this subject with one of the librarians there are not confidential- I doubt they could be as they concern aspects of US law, but am open to correction.)
