The Noble Nielsen Photograph collection contains 196 snapshots of residences and businesses in Cache County (mostly Logan), Utah taken from the 1930s to the 1960s. These tax assessment photographs were kept by the county for record keeping purposes and were taped to tax assessment cards. The photos have been detached from their cards, but stored together, for the sake of preservation. The information in this inventory comes directly from the tax assessment cards. In addition, there are assessment cards without photos, building and residence snapshots with ID numbers but no assessment cards, pictures of various houses and buildings throughout Logan, and five portraits of individuals. While nearly all the cards give the property owner, the tax assessed evaluation, and the town lot number, many cards also include descriptions of the property, the date the structure was built, the building's status, its address, and/or a sketch of the floor plan.

Because only a few of the photos have an address the best way to search is by the original owner of the property. It is not always clear when the snapshots were taken. Many of the cards, however, state either the date the building was built, the year of the tax assessment, or both. Each item includes the accession number, the city (when available) the owner or name of the building (if applicable), and the address (when available). Most of images are probably from Logan.
