The fonds contains many manuscripts of Connell's own books and two which he ghosted, the memoirs of the Aga Kahn and Sir Roy Welensky. There is much correspondence with the literary, political and military world described, amounting to some 14,000 pieces. Its Commonwealth associations include Rhodesia, in the Welensky files; India, in the Aga Kahn, Wavell and Auchinleck files; Canada; Kenya and Nyasaland; and Malaysia and the defence of the British Empire. His library has, except for some rare editions, been dispersed into the Mills Library stacks. The books that accompanied the third accrual have been listed but not yet catalogued.
