This folder consists primarily of interoffice communications relating to manufacturing operations at the Edison Phonograph Works. Included are documents concerning the development of a motion picture projector called the "super kinetoscope." Also included are items pertaining to the fire of December 9, 1914, that destroyed or damaged more than half of the buildings in the West Orange laboratory complex. One document announces Edison's intention "to establish an entirely new system of manufacturing Phonographs when he moves back into the old buildings." Other items refer to a reduction in the production schedule for the Amberola 30, one of Edison's cylinder phonographs, and the use of the old Federal Storage Battery Car Co. building in Silver Lake, New Jersey, for cabinet refinishing work.

Approximately 60 percent of the documents have been selected. The unselected items consist primarily of letters of transmittal and acknowledgment, meeting announcements, and routine correspondence concerning financial matters.
