This series consists of records that were original personal fonds and collections acquired and preserved by the Riverview Hospital Historical Society's during its existence. It contains the personal collections of nurses, doctors, general staff, British Columbia's first Provincial Botanist, and a patient at Riverview Hospital. Each file includes records such as study notes, photographs, ephemera, correspondence, newspaper clippings and pamphlets.

The series consists of 15 files, each corresponding to its original creator or donor: Ken Baker, Loretta Barnet, Ultan Patrick Byrne, Jean Campbell, Edna Colvin, John Davidson, Sheila Dumore, William Headridge, Alyce Hockin, Lois Kaldestad, Catherine Murray, Judy Pendry, Dorothy Pocock, Hazel Shepard, and Georgina Bernice Petty.

The fonds consists of four Annuals (1944-1947) from the School of Nursing, Provincial Mental Hospital, Essondale as well as a selection of graduation portraits from the School of Nursing. The fonds also includes a photograph of the Essondale Medical Staff and the Superintendent of Nursing (Mona E. Parsons). Finally, the fonds includes a graduation diploma, transcript, and staff card for Helen Regehr.

The subseries consists of photographs thought to have been taken by W.J.Moore although it is possible they were taken by another photographer. The assumption of provenance has been assumed based on the context in which the negatives were found. It has not been possible to confirm. The photographs depict the buildings, livestock, farm workers (likely Essondale patients), and employees of Colony Farm and Essondale (Riverview Hospital). The subjects consist primarily of cows and horses, as Colony Farm was known across the province for the quality of its livestock. It was awarded a master breeder shield in 1930 from the British Columbia Branch of Holstein Canada. Many of the agricultural photographs also show Essondale's West Lawn building at various points in its construction.

The fonds consists of two scrapbooks and one wooden name plate. The scrapbooks were put together by Dr. Thomas G. Caunt, who worked at Crease Clinic and the Provincial Mental Hospital, Essondale, starting in 1935. He created the scrapbooks for his son and daughter as a record of his employment.

The scrapbooks detail significant moments of Caunt's medical career and personal life during 1934–1968, as well as various events at Essondale Hospital, including the installation of the BC Tel telephone exchange. A significant portion of the scrapbook documents the trips Caunt took in 1949-1950 to move geriatric patients to the new Homes for the Aged in Vernon (Dellview) and Terrace (Skeenaview).

The series consists of records created and accumulated by Cunnings and reflect his personal and professional interests. These records were accumulated by Cunnings for the purposes of reference and posterity rather than documenting the activities of the District of Coquitlam Parks and Recreation Department during his tenure.

The personal records consist of a letter of appointment as well as a selection of documentaries used by Cunnings as reference. His professional records contain photographs, ephemera, and correspondence generated in the course of Cunnings' positions as a gymnastics teacher at Our Lady of Lourdes, the Division Head of Essondale's Crease Clinic Recreation Therapy Department, and as a founding member of Coquitlam Search and Rescue (SAR).
