The bulk of Gill's papers concern his consulting work for the mining industry and for government. Only two small files relate to his teaching career. Gill's work as mining consultant is documented by 124 maps, 48 designed by Gill himself, showing structural geology of various regions in eastern Canada, and mineral deposits of gold, iron, zinc and molybdenite, not only in Canada, but also in the Malartic gold fields in Peru (1929-1968). The papers also contain his report on iron ore in Labrador (1929) and two reports by W.F. James and J.E. Gill to the Newfoundland government, assessing prospects for gold in the Rainbow and Kayak Concessions, Labrador (1933), areas prospected by R.B. D'Aigle, see his papers, Section IX: Professions And Trades. IX). Three field notebooks record summer research expeditions (1935, 1947-1948). Three reports by Peter Eakins, a former student of Gill, describe the Malartic mine (1951, 1955-1956); there is also a report by Eakins on the Wasa Lake Goldfield (1950), and one by J.B. Gilliatt on the Wabana Iron Mines (1949). Gill also raised a file of correspondence and reports on Newfoundland mineral resources (ca 1955-1969). Finally, there are two boxes of petrographic slides, one with laboratory reports, a box of mineral samples collected for the Québec Ministry of Mines, and 4 photographs of mining concerns with which Gill was involved. His teaching activities are reflected by a file of plans, reports and memoranda on the organization of the Geology Department Map Library (1959-1969) and an outline with some draft chapters of a student's thesis (1969).

Cruttwell's two geological notebooks contain addresses delivered by him to the Cardiff Natural History Society and other groups, notes on mineral types and their distribution, particularly in Western Britain, as well as maps and section drawings, notes and clippings.

Collection consists of an illustrated manuscript containing a map and brief guidebook to Paris landmarks, created by Nicole Allardet probably during the 1940s or 1950s. The item is inscribed to Vivienne Horne. A folded booklet on heavy grey paper, the guidebook contains twelve panels, ten of which feature a gouache illustrated vignette of a Paris landmark and a short handwritten description in white. The landmarks include the Jardin du Luxembourg, Opera House, Eiffel Tower, the river Seine, the Bois de Vincennes, Notre-Dame de Paris, the Jardin des Tuileries, the Champs-Élysées, Montmartre, and the Luxor Obelisk in the Place de la Concorde. In the centermost two panels is a simple map of Paris showing the landmarks depicted.
