Lighting system. The building is lighted throughout by direct illumination. In the working spaces, seminar 
rooms, and corridors, the fixtures are of a stock type with 
opal enclosing globes around the lamps. In the bookstack the 
fixtures at outlets in the main aisles are receptacles mounted 
on the covers of conduit fittings with small open-mouth glass shades; the fixtures in passages between the shelves consist of white-enameled steel bowl-shaped shades mounted with socket receptacles on the covers of conduit fittings. These shades are perforated with openings of various sizes and shapes to allow light from the lamps to illuminate the upper shelves, while the reflected light illuminates the lower shelves. The outlets are located about 7 feet 6 inches apart on the average, and there is a 60-watt lamp at each. The fixtures were designed and constructed after a long period of study and experiment.
       In the first floor main corridors and in all reading and 
book rooms, the fixtures were specially designed in harmony 
with the finish of the rooms. In the Linonia and Brothers 
reading room, beautiful table and floor lamps have been 
provided to assist in creating the comfortable and homelike 
atmosphere which was desired.

       Electricity is distributed to the various outlets by wires 
drawn into steel conduits concealed in the building structure.
       Lights in common rooms are controlled by tumbler
