The William Allen papers (1913-1980) consist of some printed material concerning William Allen (1849-1928), an architect, and microfilmed architectural drawings, mainly of the Layton and Kaysville, Utah, areas.

The Scott & Welch architectural collection (1914-1955) contains drawings of plans, sections, elevations, and details of buildings designed by Carl W. Scott and George W. Welch between 1914-1955. Most of the buildings are schools located in Utah; some of these schools were constructed by the Public Works Administration. Also included are plans for residences, offices, and retail businesses. Most of the drawings in the collection are executed in ink-on-linen.
