[This note covers the entire Harry F Miller File for Part III.]

The material for the years 1887-1898 consists primarily of contracts and agreements, assignments and licenses, powers of attorney, deeds, bonds, mortgages, and other legal documents. Often these items are in the form of drafts or fair copies. Included also are correspondence, often from attorneys; occasional caveats and other patent-related documents; financial documents such as bank notes, stock certificates, accounts, bills, and receipts; and various company records, such as minutes of meetings, reports, and memoranda. In addition, there are occasional affidavits, transcripts of testimony, and other litigation records.

The documents relate primarily to electric lighting, the phonograph, ore milling, electric traction, and telegraphy. There are many items pertaining to the Edison Ore Milling Co., the New Jersey and Pennsylvania Concentrating Works, the Edison United Phonograph Co., the North American Phonograph Co., the Edison General Electric Co., and other Edison companies. Among the documents for 1889 are testimony and other litigation records relating to Edison's controversy with Ezra T. Gilliland and John C. Tomlinson. Family-related legal items, especially regarding Thomas A. Edison, Jr., are also included.
