Impostor syndrome is a form of anxiety characterized by lack of confidence in one’s own knowledge and competence, the feeling that success is undeserved, and a fear that one will be “revealed” as an impostor. Because academic librarians serve as teachers and authority figures in an environment that values complex and specialized expertise, serve as liaisons to highly educated faculty, and are called upon to serve many job functions, impostor syndrome affects many librarians, especially early-career professionals. Learn how to identify impostor syndrome, how it affects us personally and professionally, and how to take steps to push back against it.
