Fonds consists of minutes, reports, letterbooks, printed material, clippings, photographs, and cartographic records. Of particular significance, is the series of General Secretary's letterbooks which documents the main period of the Society's influence and activity up to 1940. Includes some records of predecessor missionary societies, namely, annual reports of Columbia Mission and minutes of New Westminster and Kootenay Missionary Association; B.C.Y.C.A.S. annual reports and yearbooks; minutes of the Executive Committee, Theological Education Committee, and reports of the New Westminster Diocesan Committee. Collections of periodicals, books, maps and photographs, in main, constituted the Society's library and thus functioned as an information source on the Church of England in B.C. as well as B.C. in general from the late nineteenth to mid-twentieth century. Information on the Church and the Society's activities was regularly disseminated through the Society's official magazine, "Across the Rockies". Copies of the "North British Columbia Coast News", published by the Caledonia Missionary Union, also are contained in the collections.
