The Junior League of Las Vegas' Records on the Morelli House Preservation Project contains the records of the Junior League of Las Vegas and the organization's efforts to preserve the Morelli House in downtown Las Vegas, Nevada from 1997 to 2017. Records are comprised of various internal and external planning documents, research files, advertising and publicity, correspondence, grant files, and photographs. Also included in this collection are scans of original planning documents and drawings used by Las Vegas, Nevada architect, Hugh E. Taylor, during construction of the Morelli House in the 1950s.

The Yucca Mountain Site Characterization Office collection (1958-2001) was assembled through a joint effort between the Nuclear Regulatory Commission (NRC) and the James R. Dickinson Library, University of Nevada, Las Vegas (UNLV) to provide public access to documentation and correspondence about the proposed high-level radioactive waste geologic repository site near Yucca Mountain, Nevada. Materials include technical reports, contractor reports, public hearing transcripts, safety evaluation reports, environmental impact statements, emergency plans, inspection reports, licensee event reports, and general communications. The collection includes documents from several other government entities such as the Yucca Mountain Site Characterization Office, Department of Energy, Office of Civilian Radioactive Waste Management (OCRWM), Nevada Nuclear Waste Storage Investigations (NNWSI), United States Geological Survey (USGS), Sandia National Laboratories, Lawrence Livermore National Laboratory, and Los Alamos National Laboratory.
