This folder contains correspondence and other documents relating to the commercial exploitation of phonographs in the United States. Most of the items are letters to and from William E. Gilmore, president of NPCo. Included are letters pertaining to the manufacture, distribution, and sale of phonographs, as well as correspondence about litigation, patents, and other legal matters. Among the documents for 1900 are letters concerning contracts for the manufacture of cylinder record masters and machine tools; arrangements for the production of recordings of the evangelist, Ira D. Sankey; and the sale of phonographs in Chicago, Pittsburgh, San Francisco, and elsewhere.
