The Howard Hughes Public Relations Reference Files (1931-1997) were compiled by Richard "Dick" Hannah, vice-president of the Los Angeles public relations firm Carl Byoir & Associates, which was hired to direct public relations for Hughes’ companies. The collection is primarily composed of newspaper clippings organized into reference files. A significant number of the files contain articles about Howard Hughes’ personal life, the operations of his companies, and legal and political disputes involving Hughes and his companies. The files also document a range of other subjects related to his business ventures, including aviation, aerospace, defense industries, motion picture studios, film stars, communism in Hollywood, and the House on Un-American Activities Committee (HUAC).

He also collected newspaper clippings about the activities of print media outlets, columnists, radio-television stations, current and former employees, and competitors.
