The University of Nevada, Las Vegas Special Collections and Archives has been strategically working to increase the discoverability, visibility, and access to collections related to marginalized communities in Southern Nevada. In the first stage of this grant-funded Wiki project, over 60 archival collections and 80 oral histories, including related people, businesses, and events associated with the Las Vegas LGBTQ+ community, have been contributed to Wikidata. In this presentation, the author continues this work by introducing UNLV's Special Collections Wiki project, "LGBTQ Hidden Histories." The presentation will discuss ongoing efforts to create, expand, and enrich linked data about the Nevada LGBTQ+ community, address challenges faced during entity extraction using archival materials, and conclude with a linked data visualization exercise using Wikiframe-VG (Wikiframe Visual Graph).
