In response to Jim Blanco's query about rollographies, I have
a database of nickelodeon and orchestrion rolls for styles
A, G, H, 4X and "O" rolls.  In the September/October 2016 edition of
the MBSI Journal, "Mechanical Music" (in the "Nickel Notes" column),
I discussed several other rollographies and the people that compiled
them.

My database is a Microsoft Access application and is not available
in print form although I am always happy to help anyone seeking
information.
