I need to submit a revised score, but I I'm a bit confused of following the right process to accomplish this. The score I need updating is this one: http://imslp.org/wiki/Special:ReverseLookup/65172 When I click on the file ID#, I land on this site: http://imslp.org/wiki/File:PMLP132663-Als_der_g%C3...

Thank You for the reference.

IMSLP #21960: Mozart Fantasia in Dmin.
Mozart Album: Zongorára (pp.29-32)
Budapest: Zeneműkiadó Vállalat, 1951.

I would expect this to be Non-PD US, yet it's status is PD. What is the rationale here?
