The records of the Chief Clerk's Office, primarily correspondence and reports, detail the operations of the Copper Range Company and Champion Copper Company in Painesdale. There is also information on the Employees' Aid Fund, Copper Range Electric Company and Copper Range Band (Chief Clerk E. W. Kruka was its secretary). There is some overlap with the General Manager's Office Records (Subseries VII) and William H. Schacht's Files (Series VII, Subseries V).
