The papers held at Churchill Archives Centre range from Hawtrey's early days in the Treasury to his death in 1974, and include Treasury Papers, Chatham House papers, correspondence, articles, reviews and unpublished manuscript material. It is an extremely full and valuable collection and contains extensive correspondence with Keynes and other leading contemporary economists. There are also some letters from Bertrand Russell written in 1908.

It should be noted that in Sections 10 and 11 (Correspondence), the letters from Hawtrey are in the form of drafts or carbon copies, and that with the correspondence there are frequently copies of the papers which are being discussed.
