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

The 26-volume set, commonly known as the Warren Commission Hearings, was published by the United States Government Printing Office in 1964. These volumes were commissioned following the assassination of President John F. Kennedy to document the evidence and testimony gathered by the commission chaired by Chief Justice Earl Warren. The collection was designed to serve as an exhaustive public record of the investigation, preserving thousands of pages of interviews, exhibits, and forensic data for historical scrutiny.

The publication represents a monumental effort in administrative transparency, though its design and content have been the subject of intense academic and public debate since their release. While the commission intended for these volumes to provide a definitive account of the events in Dallas, the sprawling and often contradictory nature of the documented testimonies provided the foundational material for decades of subsequent investigation and skepticism regarding the official findings of the commission.
