Of late, there has been an influx into IMSLP of works by Joseph Kromolicki (1882-1961), a name totally new to me up to this point. This is very attractive stuff; I haven't lived with it enough to call it "great", but it's certainly unjustly neglected. Part of that is a time and place issue; most of his work was published in Germany in the 1930s and probably didn't make it out of the country. The war also curtailed composition for his own choir (his church and then his home were bombed.) Notable are a number of offertory settings for major feasts.

Those of us in the US are probably legally bound to get these things from Anton Böhm if possible, if we want to do them. But looking doesn't hurt.
