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.
The fonds consists of Bishop Snowden's files relating to his Provincial Synod activities while he was Bishop of Cariboo (1974-1991). The records are arranged chronologically in five series: (1) House of Bishops (2) Provincial Synod (3) Provincial Council (4) Provincial Committees and (5) Vancouver School of Theology (VST). The series include minutes, reports and correspondence.
Includes minutes of Board of Trustees and various committees; correspondence of the Superintendents, primarily Alan D. Greene, the Secretary-Treasurer and the Chaplains; some architectural plans of ships, and copies of the Mission's official publication, "The Log of the Columbia". Registers refer to numerous geographic locations, but most of them are arranged by ship rather than by place.
