The Howard H. Baker Jr. Addendum is composed of six subgroups: Legislative/Political, Administrative, Public Relations and Press, Campaign, Personal, and Audiovisual.

SUBGROUP I: LEGISLATIVE/POLITICAL, 1856-2004 (bulk 1966-1996) - This subgroup contains materials created or collected by Howard Baker and his various staff, throughout his legislative career, his time as White House Chief of Staff (1987-1988), and his involvement in the 1990s and early 2000s with international, national and state politics. However, it does not include any documentation from his appointment as US Ambassador to Japan. The Legislative/Political subgroup comprises seven series:

SERIES A: SUBJECT FILE, 1969-1977 - This series contains correspondence, memoranda, reports, notes, clippings and reference material covering a range of legislative issues. As in the Legislative "Subject File" series in the main accession of Baker's papers (MPA.101), files have been grouped into subseries under broad subject headings commonly used in the U.S. Senate. The subseries here are Congress, Defense, Energy, Environment, Foreign Affairs, Health, Judiciary and Labor.

SERIES B: CORRESPONDENCE, 1965-1992 - The correspondence series includes letters, memos and notes mainly between Baker and other members of Congress, but also with legislative and executive staff, other elected and appointed officials, and members of the public. The materials span Baker’s legislative career, his time as White House Chief of Staff, and documents some of Baker’s post-legislative interests and political activities.

SERIES C: WATERGATE, 1973-1975 - Contains mostly news clippings, press releases and drafts of statements. The CIA file dated January 21, 1975, also contains memoranda and correspondence with Terry Lenzer and a few memoranda on CIA issues.

SERIES D: LEGISLATIVE ACTIVITY, 1967-1984 - The Legislative Activity Series, while covering nearly the extent of Baker's legislative career, contains an incomplete record of legislative activities. This includes Baker’s voting record and congressional record clippings not already contained in the main accession of Baker's files (MPA.0101).

SERIES E: NATIONAL POLITICS, 1856-1872, 1956-2004 – This series contains correspondence, reports, research material and other files documenting Baker’s involvement with the Republican National Committee and the campaigns of other Republican senators. It also includes some material relating to the 1980 presidential election.

SERIES F: TENNESSEE FILES, 1966-1996 – This series includes correspondence, reports and other materials. Earlier files (through roughly 1988) concern Tennessee-based projects as well as political surveys. Later files (1991 and on) cover Baker’s involvement in the campaigns of other Tennessee politicians, Lamar Alexander being the most well-documented example.

SERIES G: PUBLICATIONS, 1946-1990 – For the most part this series includes government reports, some written especially for Baker, reflecting the Senator’s evolving interests in political movements, government service, energy, and foreign affairs.

SUBGROUP II: ADMINISTRATIVE, 1955-2003 - This subgroup contains material dealing with logistic elements of Baker's legislative and post-legislative work. It includes eight series, described below.

SERIES A: CORRESPONDENCE, 1937-1993 - Correspondence between Baker and close friends, colleagues (including presidents, and national and state politicians), and members of the public, covering a variety of political, business, and personal affairs. While much (but by no means most) of the correspondence may be of a non-legislative nature, the main difference between this correspondence series and the correspondence series in the Legislative and Political subgroup is in arrangement. The Personal Correspondence material from 1970-1987 is arranged alphabetically (while the Legislative Correspondence series is arranged chronologically). Correspondence from 1988 and later is arranged first by year and then alphabetically by folder. Only a small amount of material exists between 1993 and 2001.

SERIES B: NON-GOVERNMENTAL BUSINESS, 1937-1993 - This series contains information created or accumulated by Howard Baker in non-legislative or political pursuits. The series is broken into six subseries, each arranged chronologically.

The younger Baker worked out of Scott County and took care of local affairs while Howard Baker Senior was in Washington serving as U.S. Senator. Subseries 2: Law Office Files and Correspondence (1937-1992) contains law office materials spanning Baker’s enduring legal career. Subseries 3: Timber and Coal Lease (1945-1975), Subseries 4: Business Accounts (1966-1990), Subseries 5: Deeds (1920-1981) and Subseries 6: Newstar (1990-1993) all contain material about Baker’s various investments.
