The sheet music file you tried to request was derived from works copyrighted and published in the USA prior to the start of the year 1923. As such, those works should be in the public domain in the USA. However, copyright laws vary considerably in other parts of the world, and the public domain status of these works may be different in other countries.
Therefore, I request that these files only be used where US copyright law (under which the original sources these files derived from are in the public domain).
The files are password protected, with username and password both ForUseInUS (please note is case sensitive), and by supplying that password you agree not to distribute these files outside the US, and to accept all liability regarding the public domain status or any other suitability of the documents.
NOTE:
Although I have tried to ensure these files are in the public domain in the US, I can make no guarantees to this, and you use and/or distribute them (even in the US) at your own risk.If you are a copyright holder and believe that one of more of the sources these files are derived from are NOT in the public domain, please contact me as soon as possible.
