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 Junior League of Las Vegas Records (1940-2023) contain annual reports, fundraising information, training manuals, articles, minutes, photographs, scrapbooks, cookbooks, and other operational and working files that document the activities of the Junior League of Las Vegas (JLLV). Also included is documentation for advocacy projects the JLLV was involved with, such as Drug Abuse Resistance Education (D.A.R.E.), Safe Haven, the Ronald McDonald House, Read Aloud, and Literature Awareness Program for Children. Other records in this collection document JLLV's fundraising efforts such as the Repeat Boutique, Holiday Coffees, annual benefits, luncheons, and sales of their cookbooks. Also included are scrapbooks and issues of their newsletter The Sage.
