The U.S. federal government depository library program distributes government publications to libraries which make the information available to the public. Alderman Library was designated a federal depository library in 1910—shortly before World War I began. Through flyers, posters, and other publications the federal government promoted support for our Allies and a spirit of sacrifice on the part of every American—encouraging the “Army of 100,000,000” that would eventually win the war. The mission of the federal depository library program is to preserve all of these publications. Many of the materials in this exhibit were drawn directly from the Alderman federal depository collection.
