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

Published in 1964 by the U.S. Government Printing Office, this multi-volume set documents the testimony and evidentiary records compiled by the President's Commission on the Assassination of President Kennedy, commonly known as the Warren Commission. Established by executive order shortly after the November 1963 assassination, the commission was tasked with investigating the events in Dallas and determining the circumstances surrounding the death of the president and the subsequent killing of Lee Harvey Oswald.

The publication of these hearings was designed to provide a transparent, comprehensive, and exhaustive record of the commission's findings for the public and historical archives. These volumes contain thousands of pages of interviews with witnesses, forensic analysis, and investigative reports. While intended to serve as the definitive final word on the investigation, the dense and contradictory nature of the documented testimonies has ironically become a cornerstone for researchers, scholars, and critics who continue to debate the official conclusions decades later.
