Biographical and personal papers include a little material from Wager's schooldays and his early notebooks of natural history and geological observations. His later appointments and applications for posts are also recorded. Expeditions and research material is by far the most extensive in the collection. It is presented alphabetically by territory, East Greenland being the first as well as the most important. The organisation and logistics of expeditions, especially the 1935-1936 East Greenland expedition led by Wager, are chronicled in detail, backed by diaries, reports and later correspondence. The field notebooks, catalogues of rock specimens, and the investigative analysis which continued, in collaboration, for almost thirty years are also recorded. Similar material, in somewhat less detail, is found for other areas, notably the plutonic rocks of Rhum and Skye, and for the Himalayan Geology accomplished on the 1933 Everest expedition. The field excursions for students at Reading, Durham and Oxford Universities are also documented.
There are records of Wager's university teaching at Reading, Durham and Oxford Universities. Lectures material covers a wide timespan from talks given as a schoolboy ca 1920 to 1964, and includes technical lectures given in the UK and abroad on all aspects of Wager's scientific interests in layered intrusions, geochemistry and geochronology, and also many less formal talks to non-professional audiences interested in the expeditions to Greenland and Everest. Publications material includes drafts and correspondence relating to Layered Igneous Rocks, Wager's major collaborative work with G.M. Brown that he did not live to see published. Societies and organisations material includes records of Wager's long service on the Royal Society's British National Committee for Geodesy and Geophysics Vulcanology Sub-committee. There is scientific correspondence with the research material to which it refers and some personal correspondence from family and friends including Cambridge contemporaries and acquaintances. There is considerable non-textual material including not only photographs and slides of Wager's expeditions but also the original drawings and maps made on his early Greenland visits in 1930-1931 and 1935-1936.
An Appendix lists personal and geological diaries 1925-1964, which currently remain in family hands.
