The material is presented in the order given in the List of contents. It covers the period 1926-1999 but the bulk of the material dates form the latter part of Clarke's career.
Section A, Biographical, includes a number of autobiographical account, and there is significant material relating to honours and awards Clarke received. There are diaries including one from student days in 1926. There is a little family material, chiefly relating to his grandfather and father and their roots in Leicester. Also included is information relating to deposits of archival material and butterfly specimens elsewhere.
Section B, University of Liverpool, is very slight. It includes Clarke's account of the Department of Medicine 1958-1972 and his annual research reports to the University 1991-1998.
Section C, Medical research, is unfortunately not extensive. It does include documentation of Clarke's post-war research on nutritional deficiencies in British Prisoners of War. However, the bulk of the material dates from the 1980s and 1990s and relates to Clark's post-retirement studies of longevity and pregnancy in diabetes.
Section D, Lepidoptera research, documents some of Clarke's work on butterflies and months 1950-1998. Although there is a slightly better coverage of Clarke's work over many decades than in the medical research section, again the bulk of the material dates from the 1980s and 1990s. Topics included are work on Paplio dardanus and moth pheromones. There is also material relating to import licenses and permits to bring lepidoptera into the UK, 1952-1991, which provides some indication of Clarke's research interests over time.
Section E, Publications and lectures, covers both medical and lepidoptera work. The bulk of the publications material relates to work done in the 1990s but far from fully documents Clarke's prolific output even in that decade. The publications include autobiographical reminiscences, a few papers on lepidoptera and medical subjects and obituaries and memoirs of a number of a colleagues including I.B.Sneddon, Lord Zuckerman and E.B.Ford. The section includes documentation of a number of public and invitation lectures delivered 1977-1998, Some on the occasion of an award. There is also an incomplete set of Clarke's offprints.
Section F, Visits and conferences, cover only a few of Clarke's visits and conferences 1963-1995. The two largest single components are documentation of Clarke's visit to China as a member of a Royal Society delegation in 1978 and material from a visit to Fiji in 1981.
Section G, Societies and organisations, includes seventeen British national and regional societies. The best documented are the Association of Physicians of Great Britain and Ireland, the Royal College of Physicians (chiefly Clearke's Directorship of the Medical Services Study Group and then its Research Unit) and an informal visiting group as the Medical Pilgrims. The bulk of the material is from the 1980s and 1990s.
Section H, Correspondence, has been subdivided, following Clarke's arrangement into four subsections. The first is correspondence with named individuals. This includes H.B.D. Kettlewell and U.Mittwoch. However, of particular note in this subsection are the sequences of correspondence with J.B.S. Haldane and J.S. Huxley and J.S. Huxley in which the principal correspondent is not Clarke (although he features in the correspondence with Haldane) but his Liverpool colleague and friend P.M. Sheppard. The second subsection present correspondence on specific subjects, chiefly lepidoptera and including in particular material relating to work on the moth Bison betularia. The other two subsections present sequences of later correspondence 1994-1998 arranged alphabetically, and of shorter exchanges or single letters found loose.
Section J, Non-textual material, includes an extensive collection of glass and negative photographic film slides, chiefly of lepidotera, a small number of photographs and cine and video documentaries on the rhesus work of Clarke and P.M. Sheppard.
