This unnumbered scrapbook covers the years 1880-1889 and contains clippings about electrical measurements, testing apparatus, and the uses that can be made of electricity. Among the latter are many articles about Edison's work in electricity, the controversy between Edison and Westinghouse over direct versus alternating current, and the adoption of execution by electricity. There are also a few articles about various other technologies, including Edison's acoustic inventions. Several loose clippings for 1888 and 1889 have been arranged at the end of the book. Approximately 100 pages of the book have been used. Courtesy of Thomas Edison National Historical Park.
