The vast majority of the material relates to Dent's research and clinical interests and falls into four main categories: correspondence files; files created around the publication of papers; lecture notes and symposium papers; and case/research notes. There are also smaller quantities dealing with other aspects of his career, such as the administration of UCH Metabolic Ward. The papers thus reflect most of Dent's scientific and clinical interests. This research is mainly represented by the abstracted documentation which he kept with drafts of his published papers (see section E.1) and also by correspondence about cases and clinical case notes (see section C.5). To a lesser degree they also illustrate the work at the laboratory bench which underpinned much of this research. For example, a file of unidentified paper chromatograms has been preserved (C.2/10) to illustrate one of Dent's methods of working, as described by his colleague, Heathcote, and quoted in the Biographical Memoirs of Fellows of the Royal Society, 1978: 'Paper chromatograms were not to be thrown away. They were filed and, since the colours faded, the outline of each spot was drawn in and the intensity of the colour was indicated by a number.' The way in which Dent compiled a large series of files around drafts of scientific papers also illustrates the importance of the published paper to him as a stage in the research process. An incomplete collection of reprints of Dent's published papers may be found in section E.2 of the collection.

Collections of reprints, 1891-1945, on topics including basal metabolism, temperature, radiation, hygiene, thermal adjustment and barometric pressure. These reprints were collected by Sir Charles Martin, although very little of the reprints were written by him. Many of the files contain manuscript notes by Martin, usually on other articles. Some of the reprints have been annotated.

Papers of Sir Robert McCarrison including 149 posters illustrating nutrition observations and experiments, 1913-c.1947; memorabilia including notes for speeches and letters received, 1931-1960; correspondence with Nutrition Society and Oxford University Press, 1950s; photograph album of Coonoor including the Pasteur Institute, 1920s-1930s. Letters to McCarrison from his former assistants in Nilgiri District, Mula Singh and Krishnan, on the publication of the Festschrift, can be found in B.5. His interest in deficiency diseases was aroused by his observations of the distribution of goitre and cretinism in Gilgit, where he served from 1904, and the posters in Section A illustrate his observations and experiments on the effects of diet on metabolism. A list in B.1 includes some of the titles of the posters in section A, but also mentions others not found.

The collection comprises minutes and supporting paperwork for meetings of the Committee of Management of the Audio-Visual Centre; teaching and training notes including lecture notes and questionnaires; production accounts and financial papers; shooting and activity logs and production notes; video tapes of events at the University of London; a photograph album; audio-visual reels (NOT YET CATALOGUED); annual reports and printed material including workshop handbooks, catalogues, newsletters and a review of the Audio-Visual Centre.

Reports, diaries, memoirs, photographs and memorabilia given to the Royal Army Medical Corps Museum and Library by former officers and men of the Corps. Some date back to Marlborough's campaigns of the late 17th century; there is also material relating to the continuing European and Imperial conflicts of the 18th and early 19th centuries, the Crimean War (1854-1856), the Boer War and the Balkan conflicts of the early 20th century, the two World Wars, the Korean War and other smaller conflicts thereafter.

The majority of papers in this collection concern Trowell's work on fibre, carried out in close cooperation with Denis Burkitt, exploring its role in the prevention of obesity, diabetes and coronary heart disease. There are no primary sources from the period Trowell spent as Senior Physician at the Mulago Hospital, Uganda, 1930-1958, where he was one of the key researchers into the protein-calorie malnutrition disease kwashiorkor. However, publications can be found at C.1 and the work is discussed in transcripts of taped reminiscences (A.2), and in Trowell's biography (A.5).

Section D of this list consists of papers generated by Trowell's engagement in the debate on the interface of religion and medicine.
