Either these are illegal copies or the publisher has properly obtained permission to arrange and publish (in which case I should be interested in knowing where I too might obtain permission to make copies for liturgical use in UK.

In the U.S., where CPDL servers are located, copyright lasts 70 years after the death of the composer only for works created after December 31st, 1978, which is obviously impossible as Carlo Rossini died in 1975. Carlo Rossini's works are public domain in the U.S. if they were published before 1923, or if they were published betwwen 1923 and 1964 without an appropriate copyright notice, or if copyright was not renewed through an appropriate procedure after 28 years from first publication. I'm not sure whether Carlo Rossini's publisher had targeted the U.S. as a significant market and therefore took care of the procedures to obtain and maintain the copyright status in the U.S.ajtocher wrote:by my calculation copyright in these works would naturally expire on 31 Dec 2045
