This series is composed of five subseries: Congressional, General, National, Tennessee, and White House. Folders contain a wide variety of documents including correspondence from the public with Baker's replies attached, staff notes and memos, official correspondence, press releases, and reference materials. Files of the Committee of Nine are in the Congressional subseries; Baker was the chairman of this committee which was organized by nine republican senators for the purpose of helping elect nonincumbent republican nominees to the US Senate.

The five subseries are arranged alphabetically. Folders within each subseries are arranged alphabetically and thereunder chronologically.
