The Washington Talking Book and Braille Library (WTBBL) needs diverse collections in order to meet its users’ needs. In order to expose gaps in WTBBL’s holdings, our team conducted a diversity audit of the young adult collection. We found that the authors and main characters in the collection are overwhelmingly white, cisgender, and heterosexual. We recommended ways to make the collection more representative of Washington’s population and improve the library’s subject headings. With these recommendations and the data to justify them, WTBBL will be better equipped to serve its users with diverse, representative collections.
