Photographs documenting mining activities and everyday life in Wallace, Idaho and the Coeur d'Alene Mining District. The original donation of around 200,000 images included prints, glass negatives, and film negatives including nitrocellulose film. The nitrocellulose was separated to a secure location then transferred to a more stable film, both 35 mm and larger safety film, and prints. The majority of these images were portraits, and only a sample of them were transferred with the attempt to capture at least one image of each person photographed. The nitrocellulose was then securely discarded. This reduced the collection to close to 33,200 items, many with multiple poses or shots in one item.

Portrait images are mainly studio portraits of local residents ranging from families, businesspeople, to portraits of prostitutes and criminals taken for registration with the police. Landscapes and town images include buildings and houses in Wallace and the surrounding towns as well as streetscapes and panoramic views. Most notably are images of Wallace before and after the 1910 fire and of other natural disasters.

All images are attributed to either Nellie Stockbridge or T.N. Barnard. With the exception of Frank Hess, other studio employees were not noted.

A later donation included a studio camera used by Nellie Stockbridge. The brand is Century Camera and it included some components. A note inside the tube of a lens says: damaged when received on March 12, 2003.

Due to the size of the collection, it is broken up into two finding aids, this one comprised of the majority of the portraits, and PG 8-2, which includes all of the letter series in the original numbering system, showing locations, businesses, everyday life, as well as some portraits.
