This folder contains correspondence and other documents covering a wide variety of subjects. Some of the material relates to personal matters. Also included are documents that deal with more than one subject, such as a letter about both the battery and the phonograph. Documents concerning subjects that do not fall under the main subject categories are also filed in this folder. Among the items is a 12-page letter by Alfred O. Tate discussing the affairs of various Edison companies. There are also a number of letters from George P. Lathrop, who collaborated with Edison on a science fiction novel called Progress, and correspondence from the law firm of Eaton & Lewis regarding Edison's desire to sever business connections with them. Other documents refer to security problems at the Menlo Park laboratory and to the business of the Sims-Edison Electric Torpedo Co.

All of the documents have been selected.
