Information and records about Ganz's finances as a touring pianist in Europe in 1927, his work with two piano roll companies, and his administration of piano competition awards in the late 1950s through the 1960s. Also includes versions of the Star Spangled Banner and Ganz's opinions and articles of the various arrangements of the National Anthem attempted by others over the years. Research materials are articles, clippings, and programs collected by Ganz that are not by or about Ganz. Presumably they were used for compiling information for lectures or other works.
