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

Commissioned by President Lyndon B. Johnson in 1963, the Warren Commission was tasked with investigating the death of John F. Kennedy. The resulting twenty-six volumes of hearings, published in 1964, serve as the primary evidentiary record for the commission's findings. These volumes include the testimonies of hundreds of witnesses, expert reports, and thousands of pieces of physical evidence intended to provide a comprehensive public record of the events in Dallas.

The publication was designed for transparency and archival utility, presenting a vast, dense collection of transcripts and supplemental documents without the analytical narrative found in the final report. While intended to resolve public uncertainty, the sheer scale and complexity of the documentation—often referred to as the 'Warren Commission Hearings'—became a focal point for researchers and critics alike. The design prioritizes administrative record-keeping, serving as a functional repository rather than a traditional narrative text.
