Glass Plate Negatives
odd: label: General
content: This subseries contains index cards and glass plate negatives. The index cards for the glass plate negatives are arranged numerically, by plate number, and are incomplete.  The cards provide the number of the glass plate, a description (noting front, right, left, or rear view), in some instances a date, and an abbreviation for the equipment/machine.  For example, glass plate #20900, Welt Cutting (front and right), WCN.  The number assigned to each negative is located in the upper right corner of the glass plate. In some instances there are "positive" plates.  This has been noted in the container list.  Prints found with negatives have been separated and can be found in Box 198, where they are arranged numerically. Prints were not made for all glass plate negatives. 

The glass plates consist of more than 3,700 plates and are incomplete. The majority of the plates are 8" x 10," although some are 5" x 7," and they depict primarily views of shoe making equipment and machinery. However, other subjects are also represented such as portraits of United Shoe Machinery executives, copies of ledger pages copies of drawings/blueprints (especially wiring diagrams), the arrival of trains, buildings/property of United Shoe Machinery (with directional views north, south, east and west), trucks, construction work, interior offices, employees, bicycles used by employees, and hospital interiors with operating rooms. Duplicate plates (multiple views of the same image) were weeded, and in some instances, only one plate was retained.  Some plates were badly deteriorated and they were discarded.  These plates are listed in the container list and noted parenthetically (deteriorated).  Broken glass plates were housed in sink mats, and this is noted in container list.
