This pocket notebook was used by Edison in 1910 for notes regarding experimental work and other tasks to be performed at the laboratory. Many of the entries pertain to the composition and manufacture of phonograph record blanks and to storage battery electrodes. There are also notes on tungsten lamp filaments, color photography, cement production, and storage battery performance in electric vehicles. Among the employees mentioned in regard to experimental work are Walter N. Archer, William G. Bee, Charles Dally, Ignacy Goldstein, and Walter E. Holland. The book also contains many notations of a non-experimental nature. Included are reminders about music and musicians, notes on possible names for a new large-diameter amberola record, lists of employees, and ideas for promoting Edison's storage battery among owners of electric vehicles in New York and New Jersey. Tabulated data at the end of the book provide details regarding battery production, cement shipments, projected income, battery performance summaries, and the volume of cement necessary for a poured concrete house. The pages are unnumbered. Approximately 115 pages have been used.
