While much of the literature on gender in librarianship approaches this issue at an organizational level, this qualitative study investigates how individuals working in libraries perceive their gender identities as a resource for their professional goals and how this intersects with other social identities including race and sexuality. Using a constructivist grounded theory approach to analyze in-depth interviews with 29 librarians from a variety of backgrounds, we develop four overarching themes: "Visibility and Connection to Library Users," "Credibility and Presumed Competence," "Lack of Awareness and Hyperawareness," and "Being Your Authentic Self and Concealing Yourself."
