Series consists of original still and moving photography attributed to Doug Cox from the 1970s through 2008 in support of his career as author and historian. Frequently, Cox’s images form a time-lapse continuation of the older photographs he collected for research purposes. There are many reprisals of people, buildings, landscapes, and subjects first treated in his acquired research collections. In addition to this, Cox documents many of his interview subjects photographically, and this series in large part complements his corpus of recorded interviews/oral histories and collected manuscripts.
The VHS tapes include recordings of Penticton infrastructure such as the sanitary landfill, water purification plant, recycling depot, as well as the closure of Nickel Plate Mine’s last day of operation in 1996.

Collection consists of professional photographs captured by George Albert Meeres. Geographies documented centre on the Okanagan, Shuswap, and Thompson regions with predominant coverage of Vernon, BC. A suite of photographs within the subseries provides coverage of the Armstrong Fall Fair, later termed the Interior Provincial Exhibition (IPE) during the 1940s and early 1950s. Includes a series of photos marked with association of "S.J. Ladyman" (Vernon, B.C.)

Subseries consists of a photographic and oral history record of Penticton civic life from approximately 1910 through the mid-1970s, with predominant coverage during the middle decades of the twentieth century. Materials relate to sports, cultural events, landmarks and buildings, industry, transportation & infrastructure, and agriculture. Many of the photographs can likely be attributed to the Penticton Herald, but provenance is not confirmed in all cases.
