These five notebooks were used primarily in 1913 and 1914 by William Walter Dinwiddie and Sherwood T. (Sam) Moore for notes on the varnish used for Edison disc records. One book has a few entries from 1916. Other experimenters who are identified as doing related work include Charles T. Dally, Harry R. Grimes, and Archie D. Hoffman. Included are tests of various experimental varnishes and different methods of varnishing, along with tests of how certain conditions affected the varnished record. Also included are experiments aimed at resolving specific problems, such as preventing wave formation on the records during varnishing. Some of the work in these books is related to experiments by Edison, Dinwiddie, Hoffman, and Moore in a four-book set beginning with N-14-04-30 (see Notebooks by Edison).
Two books have been selected for indications of Edison's involvement.
