The A-Board historical photograph collection consists of around 8800 images mounted onto archival boards. Most of these are either copies made from original images loaned to Special Collections, or copies from historical institutions such as the Utah Historical Society and the LDS Church Historical Division. Also included are a few original images. This collection was the first organizational scheme created by USU Special Collections. After the division moved to collection-based processing, single images that did not neatly fit into a collection were still sporadically added. The subject matter varies widely although there are numerous images from northern Utah and southeastern Idaho including Native Americans, Cache Valley, Cache National Forest, agricultural scenes, aerial views, and pioneers. Also included are photographs from Utah, Idaho, Wyoming, and Nevada including Mormon historical sites, Western railroad images (the Central Pacific, Union Pacific, Utah Northern, Denver and Rio Grande, and Oregon Shortline), irrigation and reclamation, and the cattle industry. These images are located in metal filing cabinets.
