In order to provide inclusive service, UW Libraries needs to provide diverse collections with plentiful materials by, for, and about historically underrepresented groups. Most collection diversity resources are aimed at school and public libraries. My project focused on researching how other academic libraries have addressed DEI in their collections in order to provide methods suitable for UW’s large scholarly collection. I analyzed collection development policies incorporating DEI and conducted a literature review. With information about assessment methods and strategies to obtain more diverse materials, UW Libraries has access to a menu of possibilities to enhance collection diversity.
