After a hiatus of recording my Willis upright player piano to my
YouTube channel, I have re-started to record my piano roll collection
for historical reference.  I have found information on cataloging piano
rolls but have found no reference anywhere to _citing_ piano rolls.

How does one cite a piano roll for historical reference?
