The material is presented in the order given in the List of Contents. There is very substantial documentation of sixty years' research by Yonge in marine biology but regrettably virtually no personal or biographical material or records of his university career at Bristol and Glasgow. Material relating to the Great Barrier Reef Expedition which Yonge led 1928-29, and his continuing interest in the Reef thereafter, is to be found throughout the collection. Attention is drawn to Great Barrier Reef material in the following introductory paragraphs and the detailed catalogue entries.
Section A, Diaries, presents sequences of Glasgow University pocket diaries from 1952-53 and Edinburgh University pocket diaries 1970-83.
Section B, Notebooks, documents a number of overseas visits and expeditions. There are five notebooks relating to the Great Barrier Reef Expedition including three kept entirely or principally by Yonge's first wife who died in 1945. Other overseas visits represented include the USA 1939 and 1956, Africa 1953 and 1962, Caroline Is. 1965 and Australia 1967.
Section C, Research, is by far the largest in the collection and documents Yonge's research on molluscs and coral reef ecology over six decades. There is a chronological sequence of research folders 1922-82 whose contents may include correspondence, notes, drafts, drawings, figures, photographs and printed matter. Folders containing drawings and figures only are presented in a separate sequence arranged alphabetically by subject or folder title. There are (incomplete) lists of Yonge's scientific papers at NCUACS 25.1.91/C.535.
Section D, Societies and Organisations, documents Yonge's association with a number of British and overseas organisations. The most substantial records are of the Royal Society and in particular of a joint Royal Society/Universities of Queensland expedition to the Great Barrier Reef in 1973. Yonge was chairman of the UK committee which oversaw financial and programme arrangements.
Section E, Correspondence, comprises general correspondence with scientific colleagues arranged chronologically and additional sequences kept together by Yonge on the Great Barrier Reef Expedition, 'Miscellaneous Hong Kong and Pacific Science' and Advances in Marine Biology.
Section F, Non-print material, provides important photographic records of Yonge's visits and expeditions including many not documented elsewhere in the collection. There is a comprehensive photographic record of the Great Barrier Reef Expedition including the photographs used in Yonge's 1930 book A year on the Great Barrier Reef. The section also includes maps of the Great Barrier Reef and a tape-recording 'Commentary of Lowe Island film'.
