Investigation of the Assassination of President John F. Kennedy: Hearings Before the President's Commission on the Assassination of President John F. Kennedy:

The Warren Commission Hearings were published in 1964 following the directives of Executive Order 11130, which established the President's Commission on the Assassination of President John F. Kennedy. The twenty-six volumes represent the exhaustive evidentiary record gathered by the commission, chaired by Chief Justice Earl Warren, to investigate the events surrounding the assassination in Dallas, Texas. The publication was intended to provide full transparency to the public by documenting the testimonies of hundreds of witnesses and the scientific analyses of physical evidence.

The design of these volumes prioritizes archival utility and administrative formality, adhering to the standard layout for U.S. government reports of the era. The internal typography and layout were managed by the Government Printing Office, focusing on clarity for legal and historical researchers. Upon release, the set became a foundational, albeit controversial, resource in American history, as its conclusions—particularly the single-bullet theory—have been subject to intense public scrutiny and academic debate in the decades since its initial distribution.
