Information found in the files is incomplete and contains mostly photographs, dance cards and invitations.

Photographs can sometimes tell their own story such as with the "Superdance USA" of 1981, with its succession of 4 photographs. However, many photographs are vague and do not communicate who, when, where or why. Present day dances and recreations are unaccounted for.

Information about the Supper Dance can be derived from the many press releases about the event.
