The papers were presented by Hamilton's sister, Miss Jean Hamilton, in 1957. The diaries cover most of his career and all periods afloat from 1908 to 1928. There are also diaries for journeys in the merchant ships Lagos, 1915, and in the Usaramo to Lisbon in 1924. In addition there are official reports and signals for the time when Hamilton commanded the First Cruiser Squadron and a very full collection of letters written by him to his family, 1906 to 1956. Those from 1939 are not available for inspection until 1985. There are also photograph albums of Osborne and Dartmouth, 1903 to1907 of the Durbar, 1911, and of other periods in Hamilton's life. Finally, there are lecture notes and memoranda from Dartmouth, 1922 to 1924, and papers relating to Australia, 1947.
