These documents, which cover the years 1915-1925, consist primarily of memoranda and reports exchanged between Edison and Newman Henry Holland, an engineer at the West Orange laboratory. Included are items pertaining to Edison's proposal to make "opera movies," tests of audible range finders during World War I, and experiments involving electromagnetic recordings of music. Also included are notes by Edison and an employee named Dodd regarding Dodd's duties as inspector in the Plating Department of the Disc Recreation Division. In addition, there is a note from Edison to Princeton University President John G. Hibben commenting on a quotation by the German philosopher Hegel that Hibben used in his address at the dedication of a commemorative tablet at Edison's Menlo Park laboratory.
