The Bracken papers held by Churchill College Archive Centre consist mainly of the source materials used by Andrew Boyle in his biography "Poor Dear Brendan: The Quest for Brendan Bracken" (Hutchinson, London, 1974)". In addition there is a section of xerox copies of letters from Bracken to Lord Beaverbrook made available by the House of Lords Library. M. Whitmore Richards’. reminiscences of Bracken in connection with the Union Corporation of South Africa form a third section.
