The Pueblo Grande de Nevada Manuscript Collection (1924-1983) contains journal articles, photocopies of artifact inventories, reports, correspondence, and field notes related to the Pueblo Grande de Nevada archaeological site located in the Overton Valley of Southern Nevada. The bulk of the materials are related to Mark R. Harrington's archaeological reports, journal articles, and data from sites throughout the Overton and Moapa valleys. The collection also includes materials related to the Boulder Dam Park Museum (Lost City Museum of Archaeology) located in Overton, Nevada, which housed many of the artifacts and photographs from Harrington's archaeological sites.

The Army Mapping Service Aerial Photographs of Southern and Western Nevada (1952-1956) consist of approximately 2,080 black-and-white high-altitude aerial survey photographs of Southern and Western Nevada. Two projects are represented; 109-G, covering sections of Southern Nevada and 160-BH, covering a section of Western Nevada. Also included are five composite photograph indices created from the detailed survey photographs, four index sheets showing the project locations in Nevada and other projects in the western States, and five photocopied images of composite photographs of several cities in Nevada.
