Consists of published materials, largely pamphlets and reports, from agencies in the U.S. Department of Labor and the Work Projects Administration (WPA). Though mainly national in scope, some materials specifically address working conditions in California. Although the earliest publication is 1913, the bulk is from the 1920s, 1930s and 1940s. Included is a large collection on women's work, beginning in 1921 and continuing through World War II and the post-war reconversion period. Another subject well represented is the Great Depression, including pamphlets on the New Deal and from the WPA covering the subjects of agriculture, migratory workers, unemployment, relief programs, and job training. The enactment of unemployment insurance is documented along with many alternative proposals considered in the 1930s. Material on occupational safety dates from 1922 and includes pamphlets on safety for youths and women. Early concerns about the hazards of radiation and pesticides can also be found. California economic conditions, unemployment and labor force statistics are represented. Labor material includes convention proceedings and publications from the California organizations of the AFL and the CIO.
