She explores the balance between open access and subscription models through an equity lens, highlighting the importance of author-first and choice-driven perspectives. She also explains how the librarian’s role may shift in an increasingly open environment through heightened curation and direction for researchers. Last, Bek underscores mental health’s position as a “last frontier” by unpacking the obstacles that stigma creates, and how a more nuanced and widespread understanding of mental health can help overcome these barriers.
