This address book was used by Edison as a pocket notebook. The only dated entry is for September 24, 1887, and concerns coatings for phonograph cylinders. Other entries deal with lamp filaments, meters, the electromotograph, and chemical experiments. The front cover is stamped "Addresses." The last 4 pages and back cover are damaged. The pages are unnumbered. Approximately 40 pages have been used.
