In 2020, UNLV Special Collections and Archives conducted an internal audit of collections, strategic plans, and programming in order to assess how well it is meeting strategic goals of being more inclusive and increasing diversity and representation. In a data-driven institution, how can assessment be used to advocate for resources focused on diversity, equity, and inclusion? In conducting this analysis, UNLV hoped to answer the following query: how is progress measured if the goal is to preserve stories outside the traditional narrative (white, male, cisgender, heteronormative, etc.)? This article discusses strategies for assessing diversity in special collections and archives. [ABSTRACT FROM AUTHOR]
