As librarians' instructional roles continue to evolve, metaphor can be a powerful tool through which to reflect on and at times to reframe librarians' evolving educational roles and pedagogical approaches, as they consider beliefs and assumptions about teaching and learning and about their unfolding work and identities. This article explores this potential by examining professional documents on librarians' teaching, discussing empirical research on metaphor as a tool for teacher development, examining metaphors that librarians have sometimes used to describe their pedagogical work, and sharing the author's experiences facilitating a librarian workshop on metaphor and librarians' teaching roles.
