The dated entries in this pocket notebook are from July-October 1913. The book was used by Edison to record ideas about business matters, experiments to be tried, and other tasks to be performed. Many of the items have been crossed out. The entries at the beginning of the book pertain to the finances of Thomas A. Edison, Inc., and other Edison companies, as well as to Edison\'s personal finances. Similar information can be found in PN-13-07-12, and some of the entries in that earlier book appear to have been copied into this one. The remaining entries relate primarily to the development and production of disc records. Included is data on production costs, daily production numbers, and salaries. Also included are notes and instructions about automobile starters, chemicals, batteries, cell regeneration, miner\'s safety lamps, and kinetophones.

Among the numerous Edison employees mentioned in the book are experimenters Charles T. Dally, William Walter Dinwiddie, Archiebald D. Hoffman, and Sherwood T. (Sam) Moore, principal assistants in the development of disc records; Charles W. Luhr, superintendent of the West Orange laboratory; and Carl H. Wilson, vice president and general manager of Thomas A. Edison, Inc. The pages are unnumbered. Approximately 150 pages have been used.
