As public libraries reexamine and reframe their goals and reasons for existing in a social and information context increasingly mediated by digital media, the way in which they define themselves in their mission statements reveals a range of benefits, values, roles, and institutional standpoints. This critical content analysis of 32 public library mission statements focuses on the roles and standpoints constructed and naturalized through mission statement rhetoric, including the reality claims, metaphors, subject positions, and formulas used to create them. The analysis examines who created the missions and who and what appear privileged within them, focusing especially on the assignment of agency, in light of the call for "user-centered" library services.
