These standard-size (6" x 9") notebooks cover the period 1887-1898. There are also scattered entries from the early 1900s. Most of the books were used at the West Orange laboratory, although some include work performed at other locations, including the Edison Lamp Works in Harrison, N.J.; the New Jersey and Pennsylvania Concentrating Works in Ogden N.J.; and the Edison Machine Works in Schenectady, N.Y. The books contain notes, drawings, tables, and calculations regarding a variety of subjects, including phonographs, lamp filaments, electric power, the kinetoscope, batteries, ore milling, and the electric railway. There are also numerous chemical experiments and tests of electrical instruments. Among the individuals whose work is recorded in these books are Jonas Walter Aylsworth, Charles Batchelor, William K. L. Dickson, Reginald Fessenden, James W. Gladstone, H. De Coursey Hamilton, Joseph W. Harris, John Ott, Arthur C. Payne, Franz Schulze-Berge, and Erwin Von Wilmowsky. There are also numerous notebooks generated by Arthur E. Kennelly and his assistants in the Galvanometer Room. A few books contain scattered entries by Edison. Two books in this group are not standard size but have archival "N-numbers" similar to those in the main run of notebooks.

Records not selected: Galvanometer Room Notebooks

These notebooks were used by Arthur E. Kennelly and his assistants as rough record books in the Galvanometer Room at the West Orange laboratory. The books contain notes, drawings, tables, and calculations regarding various electrical experiments, including tests of alternators, batteries, dynamos, insulation, meters, and motors for streetcars, fans, and the phonograph.

Records not selected: Schulze-Berge Notebooks

These five notebooks cover the period December 1887-January 1891. They were used by Franz Schulze-Berge for notes on his experimental work at the West Orange laboratory. Almost all of the entries are in German. The first two books contain notes, drawings, and calculations regarding various electrical experiments, including tests of batteries and a "standard pressure indicator," and two pages of notes listing books in Edison's library. The remaining books relate to the plating of wax phonograph cylinders. Brief descriptions in English of these experiments, written at a later date by Charles Wurth, appear on the first page of each book. Inscriptions on the inside front cover of the books indicate that the books were used as exhibits in National Phonograph Co. v. American Graphophone Co., U.S. Circuit Court, District of Connecticut, Equity Nos. 1076 and 1103. Translations of the books can be found in the records of that case (see Litigation Series).

Records not selected: Other Notebooks

Notebook, N-88-01-13

This notebook covers the period January-August 1888. It was used by Arthur C. Payne as a log for compounds employed in experiments on phonograph cylinders and lamp filaments. There are also scattered notes regarding results of the tests. A transcription of the cylinder experiments can be found in N-88-03-06.

Notebook, N-88-05-17

This notebook covers the period May 1888-November 1891. It was used by Charles A. Brown and John S. Emmons as a record book for experimental lamps and carbons received from the Edison Lamp Co.

Notebook, N-88-09-03.1

This notebook covers the period September-November 1888. It was used by Arthur C. Payne for notes on compounds for a flexible ("mailing") phonograph cylinder.

Notebook, N-88-11-13.3

This notebook covers the period November 1888-February 1889. It was used by Jonas Walter Aylsworth as a rough record book for phonograph cylinder experiments, nos. 857-1011. Transcriptions of these records can be found in N-88-08-23. There is also one page of calculations by Edison regarding ore milling. The book was used as an exhibit in American Graphophone Co. v. National Phonograph Co., United States Circuit Court, District of New Jersey.

Notebook, N-89-01-10

This notebook covers the period January 1889-January 1892. It was used by John J. Force to record information regarding experimental lamps sent to the test room. The lamp orders duplicate the information found in N-89-03-01.

Notebook, N-89-10-15

The one dated entry in this notebook is from October 1889. The book was used by Reginald Fessenden for notes regarding the electroplating of copper and the analysis of ores.

Notebook, N-90-03-30

The one dated entry in this notebook is from March 30, possibly 1890. The inside front cover indicates that the book was intended to be used by Harry Murry and John Joseph Force as a log book for lamp tests. However, the book contains only one brief note regarding breakage of lamps.

Notebook, N-91-00-00

This undated notebook was used by J. E. Myers as a log book for codes assigned to lamps tested by John Joseph Force and the Edison Lamp Co.

Notebooks, N-95-09-05, N-97-09-13, N-97-10-20

These three notebooks cover the period September 1895-October 1897. There is also one dated entry from August 1898. They were used by Jonas Walter Aylsworth and Francis R. Upton, probably at the New Jersey and Pennsylvania Concentrating Works in Ogden, N.J. The books contain rough notes regarding experiments, nos. 1-493, testing the amount of various grades of sand that could fit into a vessel of fixed volume (see also N-95-09-12, below). The experiments were intended to determine the viability of using sand tailings from Edison's ore milling operation in the production of cement. There are also various other scattered notes pertaining to ore milling, along with rough drawings of unidentified buildings.

Notebook, N-95-09-12

This notebook covers the period September 1895-December 1897. There are also three entries dated August 1898. The book was used by Jonas Walter Aylsworth and Francis R. Upton, probably at New Jersey and Pennsylvania Concentrating Works in Ogden, N.J. It contains rough notes pertaining to various subjects, including a series of inconclusive tests, nos. 1-25, of oils for use as a lubricant at low temperatures. Test no. 7, in Aylsworth's hand, indicates Edison's involvement in one of these unsuccessful lubrication tests. Also included are notes relating to the bricking of iron ore concentrate and to sand volume experiments, nos. 494-509, continued from N-97-10-20.
