The eight groups of notebooks (796 books) in this subseries cover the period 1911-1929, with most dating from 1911-1919. About two-thirds of the books pertain to storage batteries. There are also eighty-two books relating to cylinder and disc records, as well as nineteen containing experiments on Edison's home projecting kinetoscope and kinetophone (motion pictures with sound). In addition, there are thirty-one books that were used during World War I for experimental work for the U.S. Navy and other war-related research; eighty-one books of chemical experiments; and a few books pertaining to electric vehicles and miner's safety lamps.
Within the six largest groups, related notebooks are arranged into subgroups, often according to the name of the experimenter. Among the Edison employees whose work is represented in these books are Leroy E. Briggs, Peter C. Christensen, Charles T. Dally, Frank Detlef, Jr., William Walter Dinwiddie, Elmer E. Dougherty, Zachariah P. Halpin, John A. Hanley, George E. Hart, William A. Hayes, Charles F. (Frank) Hunter, Miller Reese Hutchison, Absalom M. Kennedy, Ludwig F. (Louis) Ott, and Selden G. Warner.
