The Civilian Conservation Corps (CCC) began in 1937, succeeding the Emergency Conservation Work agency, which started in 1933. In 1939, the CCC became part of the Federal Security Agency. It was eliminated in 1943. The purpose of the CCC and its predecessors was to provide employment in forestry and conservation work for unemployed youth during the Great Depression.
Note: CCC publications are kept in Gov Docs closed shelves, so you may ask for them at the Gov Docs reference desk.
Government Documents has a small collection of Civilian Conservation Corps and Emergency Conservation Work publications, including the following series:
Annual report of the director (FS 4.1:)
Forestry publications (FS 4.7:)
Monthly safety bulletins (FS 4.8:)
We also have Congressional hearings and reports about the CCC and ECW as well as general publications of both agencies.
Records of Emergency Conservation Work and Civilian Conservation Corps projects done in Hawaiʻi are kept in the Hawaiʻi State Archives.
