Chief Officers of State Library Agencies (COSLA) is an independent organization of the chief officers of state and territorial agencies designated as the state library administrative agency and responsible for statewide library development. Its purpose is to provide leadership on issues of common concern and national interest; to further state library agency relationships with federal government and national organizations; and to initiate cooperative action for the improvement of library services to the people of the United States.
COSLA provides opportunities for in-person convenings of State Librarians and supports the development of other State Library staff such as Library Development Heads, Continuing Education Managers and others. Chief Officers meet 3 times per year and every meeting provides an educational component. Additionally State Library staff have access to an active online community where they can share ideas and questions and learn from each other.
