Manuscripts
The Aurora Consolidated Mines Company Records, composed mostly of plans and blueprints for mine equipment, appear to be primarily from the mine's metal and repair shop. The collection is composed of one manuscript, a large number of plans and blueprints, one letter, a number of clerical documents, and two pieces of ephemera.
