Collection consists of the documentation of Cox’s career as an historian and author. The collection is comprised predominantly of photographic material. There are approximately 15,000 unique photographic images: prints in various standard dimensions (8"x10", 5"x7", 4"x6" and smaller, with some custom dimensions, predominantly in black and white; slide transparencies in black and white and colour; negatives, (120, 35mm, and 4”x5”) in black and white; digital photographs in black and white and colour contained on CDs and one hard drive.
Photographic coverage extends from the 1870s to approximately 2008, with the period 1900-1970s predominant. Original photographs by Doug Cox cover the 1970s through approximately 2008.
The collection also features audio cassettes containing sound recordings of interviews recorded in the 1980s and 1990s with associated transcriptions by Joyce Cox. Government documents (primarily Province of British Columbia, c. 1910-1960s) include topographical maps, tree farm license maps, mineral claims maps, taxation records, forestry examination sketches and other records.
Geography covered is predominantly the Shuswap, Okanagan, Similkameen, Boundary, Kootenay, Nicola and Thompson regions of British Columbia, with sparser coverage of outlying areas as well.
Themes treated include mining, ranching, forestry, agriculture and orchard cultivation, industry and infrastructure, landscapes and cityscapes, sports and recreation, community life, and family documentation.
