The UT Libraries and the Howard H. Baker Jr. Center for Public Policy signed a memorandum of understanding in April 2005 that created the Modern Political Archives. Several groups of political papers currently held by the UT Libraries formed the core collection, including the papers of Senators Howard H. Baker Jr., William Emerson Brock III, Cary Estes Kefauver, and Fred Dalton Thompson; those of United States Congressmen John J. Duncan Sr. and Howard H. Baker Sr. and Congresswoman Irene Baker; gubernatorial papers of Winfield Dunn and Donald Sundquist; and the papers of Tennessee State Senator Ben Atchley. Staff would continue to seek papers of twentieth- and twenty-first century Tennessee political leaders for the archives, located in the Baker Center. The Baker Center managed the archives until the reorganization of the center, when full management and responsibility for them returned to the UT Libraries.
