Florida AFL-CIO was formed in 1958 with the merging of the Florida American Federation of Labor and the Florida Congress of Industrial Organizations. The collection, 1965-1968, consists of correspondence, minutes, financial documents and printed materials. Correspondence illustrates such primary concerns as labor's role in education; state and national legislation; opposition to the Taft-Hartley Act and the Landrum-Griffin Bill, and its support of Congressman Claude Pepper.

The records of the United Association of Plumbers and Steam Fitters of the United States and Canada, Local 72 (Atlanta, Ga.), 1952-1972, consist of correspondence dealing primarily with disputes with other unions over jurisdictional limits and with the entrance requirements, training, examination, restriction and certification of apprentices.
