Could someone check the date (and hence, the copyright status).
Niemann's opus numbers appear to be strictly chronological, and this opus number would place it sometime in 1917. It's possible this was re-typeset, or composed during the war and only published in the 20's.
- It does appear in the 1927 U.S. Catalog of Copyright Entries (on Hathi Trust here) but it is listed as neu rev. ausgabe so I'm assuming an earlier edition is hiding out there. Can't seem to find a renewal for it in the volumes for the mid-1950s but Hathi's text search isn't infallible. --Cypressdome 03:11, 4 July 2011 (UTC) The earlier version of Op.46 does appear in Hofmeister's Handbuch for the years 1914-18 here. --Cypressdome 03:25, 4 July 2011 (UTC)
