This notebook was used by W. Jones in 1911 for notes on experiments involving the shellac used to coat the Edison disc records that would be put on the market in 1912. The object of the experiments was to reduce blisters, smears, and other imperfections. The notes indicate that A. Petit (either Ademor N. or Albert O.) collaborated with Jones on the new disc records. One note by Edison has been inserted into the book. The front cover is labeled "Shellac # 2064" and "W. Jones, Chemical Laboratory." The pages are unnumbered. Approximately 50 pages have been used.
