The collection contains correspondence and related documentation that shed light on aspects of Griffith's political career and public life and his personal relationships with his family and friends. Among the papers is his private correspondence with his wife Maud and son Nevin, written during periods of imprisonment (1916-21) and during the course of the Treaty negotiations when he was based in London, and his final statement written in 1922. Also included are photographs (both private family photographs, alongside studio portraits and news agency photographs of Griffith and other Irish political figures attending public events and meetings and the funerals of Griffith and Michael Collins), posters (largely commemorative items published following his death in 1922), portraits of Griffith in both pencil and in oils, books from his library, many of which contain ownership signatures and inscriptions dating from his imprisonment in Reading and Gloucester jails and his time as President, newscuttings, and his own copies of the newspapers he edited, notably 'The United Irishman', 'Scissors and Paste', 'Nationality', 'Éire Ireland' and 'Sinn Fein'.
