These six books were used by Absalom M. Kennedy during 1913-1914 primarily for experiments on the kinetophone. There are entries pertaining to the making of kinetophone recording outfits, adjustments based on recommendations or testing, and experiments with various motors and other parts. There are also recording tests to determine the optimal stage positions for actors and props as well as other filming conditions. Some of Kennedy's notes describe meetings of the "kinetophone experimenters" and the tasks assigned to them. A few relate to the recording experiments in Notebooks by Edison and Other Experimenters -- Recorder and Recording Experiments -- A. M. Kennedy Books. Several entries contain notations that Kennedy was reporting to Miller Reese Hutchison. In some cases, he received instructions directly from Edison on projects to be undertaken, along with comments and suggestions. The notes indicate that Adolph F. Gall, L. E. Hammond, Daniel Higham, Charles W. Luhr, and George J. Werner were doing similar kinetophone-related projects. A few experiments by Kennedy on kinetophones and motion picture film, as well as references to kinetophone demonstrations, can be found Notebooks by Edison and Other Experimenters -- Recorder and Recording Experiments.

The five books with indications of oversight by Edison have been selected.
