ALA's Membership Statistics by Division, 2000-Present

ALA has eight divisions. Divisions are membership units that focus on types of libraries, such as public or academic; on types of services, such as children's, technical, or user services; or on particular areas of interest, such as information technology or management. Divisions offer programs and publications; collect membership dues; hold national conferences, institutes, and workshops; and elect or appoint their own governance structure, committees, task forces, and discussion groups as outlined in Policy 6.4. You must be a member of ALA to join a division.
