Whilst Sawer considered his papers to be of 'marginal importance', the collection, which dates back to the late 1930s, contains some interesting original material, including diaries, draft legal opinions, autobiographical writings, and correspondence with prominent individuals. Sir John Latham, Sir Owen Dixon, Sir John Barry and Lord Denning, and other politicians and judges number amongst Sawer's many noted correspondents on constitutional matters. Also included are cuttings documenting his long running 'Between the lines' newspaper column, and radio transcripts from his involvement with the Short Wave Propaganda Division of Radio Australia during World War II.
