Between 1921 and 1934 several innovations were made. A few of the outstanding are as follows: The eighth floor was remodeled and raised to provide room for the Cafeteria, Harding Hall, recreation rooms, rest rooms, and large space for productive work. The Cafeteria serves around 2,800 meals daily, and Harding Hall, seating 1,200, is devoted to social activities of employees and may be quickly converted into a ballroom, a motion-picture theater, or a forum. Recreational activities include orchestra, baseball clubs, bowling alleys, dances, moving pictures and lectures, annual excursions, and similar affairs. The photo-engraving plant was also added as one of the new mechanical departments and is also located on the eighth floor. A roof garden was built, covering practically the entire building. The emergency hospital was enlarged, and wards for men and women were provided, with beds, toilets, and shower baths. Two hundred apprentices received training for occupational pursuits in the various printing and bindery trades represented in the Office. A testing laboratory was established in the Office for the purpose of standardizing all materials, supplies, and stock used in the manufacture of printing. The boiler and generating rooms were abolished, and the purchase of electric current and steam from the Capital Power Plant was started. Since 1934, under the direction of Public Printer A. E. Giegengack, the Government Printing Office has continued to grow not only in size but also in public esteem. Under his leadership, appropriations for a much-needed building program were granted by Congress, and the erection of a warehouse and an eight-story, red-brick addition to the main Printing Office building was accomplished. The cost of this building program, which included buildings, machinery and equipment, furnishings, the expense of moving, and other incidentals, amounted to $7,700,000. Among the many noteworthy improvements inaugurated for the betterment of service to the Government, to the public, and to the 5,500 employees of the Office, are the following: The establishment of a department of typography, through which there are incorporated into Government printing the accepted improvements in the field of typography; the standardization of a type-metal alloy for all type-casting machines; the installation of a more efficient cost-finding and pay-roll bookkeeping system; the reestablishment of the Government Printing Office Apprentice School; and encouragement of greater employee participation in all social, fraternal, and welfare activities sponsored by the Office. Uncle Sam’s Book Shop sold 10 million copies from its list of 65,000 publications in 1937. This department is called the Office of the Superintendent of Documents, which is located in the Government Printing Office building, and these Government publications, covering almost every phase of human endeavor, are for sale to the public at a reasonable price.
