The John Mitchell Papers, ca. 1876-1931, comprise 189 boxes, 130 linear feet, that document his many labor and civil affiliations, especially as President of the United Mine Workers of America (UMWA), 1898-1908. The papers are organized into six series: Correspondence, ca. 1885-1931; United Mine Workers of America, Minutes, Proceedings, Constitutions, and Reports, 1891-1908; Miscellaneous Minutes, Proceedings, and Reports, 1914-1919; Printed Matter, 1876-1918; Photographs, 1896-1924; and Miscellaneous and Unprocessed, ca. 1884-1924. Significant persons, events, and conditions of the ‘Gilded Age’ are revealed, especially in the UMWA material, regarding such watershed issues as standardized wages, working conditions, and collective bargaining.
