Excerpt from the Preface to Volume 1: "Mr. Jefferson having, by his last will and testament, bequeathed to his grandson, Thomas Jefferson Randolph, all his manuscript papers, Congress, by an act of the 12th of April, 1848, made an appropriation for the purpose of purchasing them for the Government; and, by the same act, an additional appropriation was made to print and publish them under the direction and supervision of the Joint Committee on the Library. It is under the authority of this act that the present publication is made."
