This notebook was used by Edison during May 1916 for notes on expeiments to improve the surface quality of Edison disc records. The entries pertain primarily to experiments 1097E through 1137E; there are also lists of other experiments and tasks to be performed. Included are tests involving different presses and varnish compounds, variations in the number of coats and methods of applying the varnish, and differing amounts of pressure and baking schedules. Flaws and successful results are both noted. Also included are notes are on inspections of discards, along with comments on edging experiments. One notation indicates that the results of experiment 1134 were reexamined in November 1916. Some notes are in the form of instructions to Sherwood T. (Sam) Moore or Archie D. Hoffman. Inserted into the book are two loose items, including a note by Edison in regard to Experiment 1134. The front and back covers are labeled \"14.\"" The pages are unnumbered. Approximately 140 pages have been used."
