Étude sur les notes de passage (Koechlin, Charles)
It is unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (like China, Japan, Korea and many others worldwide). As this work was first published before 1923 or failed to meet notice or renewal requirements to secure statutory copyright, it is almost certainly public domain in the USA as well.
Paris: Max Eschig, (1922).
This file is part of the Sibley Mirroring Project. There is a copyright date, on the cover, which is missing from this scan. "n.d." cannot be used just because the copyright date is missing from the scan!. . This is the 6th edition, so it is not the "first publication". (Still sold by Eschig, ME 1218.) Amazon claims this is only Volume 1. (No earlier edition than the 6th seems traceable though. Maybe a different title was used.)
