The John Wittwer Collection on Agriculture in Nevada (1898-1972) contains the professional papers and records of John Wittwer in his capacity as an Agricultural Extension agent for the University of Nevada from 1921 to 1954. The records are primarily annual reports containing text, photographs, newspaper clippings, and charts that provide a rich chronicle of the conditions of agriculture and ranching in southern Nevada from 1898 to 1972, with the bulk of the material dating from 1929 to 1955. These conditions span water issues, such as flood control and irrigation, to the general difficulties of sustaining agriculture and viable food production in a desert environment. The reports come from the Agricultural Experiment Stations in Clark and Lincoln counties and most contain both a statistical report and a narrative summary.

The Jamey Stillings Photograph Collection (2009-2019) is primarily comprised of photographs taken by professional photographer, Jamey Stillings, of the Mike O’Callaghan-Pat Tillman Memorial Bridge and the Hoover Dam project, the Ivanpah Solar Electric Generating System project, and the Crescent Dunes Solar project. The Mike O’Callaghan-Pat Tillman Memorial Bridge and the Hoover Dam project depict the construction of the Mike O’Callaghan-Pat Tillman Memorial Bridge from 2009 to 2012. The Ivanpah Solar Electric Generating System project depict aerial views of Ivanpah Solar in the Mojave Desert of California from 2010 to 2014. The Crescent Dunes Solar project consists of a range of aerial and ground-based work documenting SolarReserve's Crescent Dunes Solar, a 110MW concentrated solar plant with molten salt storage near Tonopah, Nevada, from 2014 to 2015.
