This folder contains correspondence and other documents relating to electric lighting and power. Included are reminiscences of Edison's work on electric lighting during the 1880s, along with offers of historic equipment of interest to him. Also included is a letter regarding a copy of Puck from 1879 containing a cartoon drawn by Joseph Keppler entitled "A New Light to the World." Among the correspondents for 1916 are Harry L. Keefer and Samuel N. Keefer of Sunbury, Pennsylvania, where the first three-wire distribution system was installed in 1883, and William S. Andrews, an electrical engineer who was closely involved with the Sunbury central station.

Approximately 30 percent of the documents have been selected. The unselected documents include invitations declined by Edison, unsolicited offers of inventions or improvements, and technical or commercial questions that were redirected to electric companies. Most of the unselected correspondence received no answer or a form letter stating that Edison was no longer involved in the electric lighting business.
