Journal clubs are meetings where participants engage in discussion or appraisal of professional literature and research. This study investigates the perceived value of librarians' participation in journal clubs. Using a hermeneutic dialectic process, we built a construction of the value of journal club participation based on interviews with academic librarians. In the construction, we demonstrate that librarians and their organizations benefit from the informal professional learning that takes place in journal clubs, by developing professional knowledge, building and strengthening communities of practice, increasing research capacity, and closing the research-to-practice gap.
