 In November 1964, two months after the publication of its 888-page report, the Commission published twenty-six volumes of supporting documents, including the testimony or depositions of 552 witnesses and more than 3,100 exhibits.All of the commission's records were then transferred on November 23 to the National Archives.The unpublished portion of those records was initially sealed for 75 years (to 2039) under a general National Archives policy that applied to all federal investigations by the executive branch of government, a period "intended to serve as protection for innocent persons who could otherwise be damaged because of their relationship with participants in the case."
