Work at main circulation desks in large academic and public libraries involves the ability to manage increasing service demands from patrons, colleagues, and the organization's administration. The perception of circulation as a catch-all department, handling responsibilities that do not fit neatly into other areas, can make this work feel like "emptying the litter pan." This presentation discusses the importance of circulation as the professional face of the library and its centrality to effective and efficient library service in the face of challenges involving mission, perception, and funding.
