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 ca.1870 to approximately 2008, with the period 1900-1970s predominant. Original photographs by Doug Cox cover the 1970s through approximately 2008. A significant proportion of photographs not attributed to Cox are copies. Many are reciprocally described via resources available via Okanagan Archives Trust Society.
The collection also includes audio cassettes containing 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.
