Investigation of Improper Activities in the Labor Or Management Field: Hearings Before the Select Committee on Improper Activities in the Labor Or Management Field, Eighty-fifth-Congress, First and Second Sessions-[eighty-sixth Congress, First Session] Pursuant to Senate Resolution 74, 85th Congress-[Senate Resolution 44, 86th Congress].

These hearings were commissioned in the late 1950s by the U.S. Senate Select Committee on Improper Activities in the Labor or Management Field, commonly known as the McClellan Committee. Established in 1957, the committee was tasked with investigating corruption, racketeering, and organized crime infiltration within labor unions and management. The resulting volumes provide an exhaustive public record of the testimony collected during these high-profile inquiries.

The documents were curated and published by the U.S. Government Printing Office as an official congressional record. The design follows the standard utilitarian aesthetic for mid-century federal legislative reporting, prioritizing clarity and archival durability over visual flourish. The volumes were intended for distribution to libraries, legal scholars, and government officials, serving as the primary source material for the subsequent legislative push that culminated in the Labor-Management Reporting and Disclosure Act of 1959.
