The arrangement of the papers reflects the filing system used by Clementi himself. The papers shelfmarked MSS. Ind. Ocn. s. 352 / 1-17A (17 boxes) were originally kept in box files with those numbers and are clearly the papers that Clementi considered to be most important, comprising telegrams, reports and letters sent between himself, the Colonial Office and the Foreign Office representatives in China during his period as Governor of Hong Kong. Other letters from this time are to be found in MSS. Ind. Ocn. s. 352 / 17B-20 (4 boxes). This includes both personal and official correspondence.

MSS. Ind. Ocn. s. 352 / 21 (1 box) holds mainly personal letters, with a few official items.

MSS. Ind. Ocn. s. 352 / 22-24 (3 boxes) contain the texts of speeches made by Clementi between 1923 and 1945 and thus cover his time in Ceylon and Malaya as well as his service in Hong Kong.

MSS. Ind. Ocn. s. 352 / 25 (1 box) holds a file labelled 'Anglo-Japanese Relations in the Far East' which dates from 1926 to 1933 and contains memoranda and reports on British and Japanese reactions to events in China.

MSS. Ind. Ocn. s. 352 / 53 / 2-5 (4 files) includes Clementi's commission as Governor in 1925 and some official papers.
