The ACRL Guidelines for Distance Learning Library Services recommends that every library develop a written profile and a written statement addressing the needs and outlining the methods by which progress can be measured. Many libraries do not have a written plan, and occasionally at such institutions, services for distance-education students suffer as a consequence. In 1998, the University of Iowa Libraries instituted a written plan for developing library services for its off-campus students, and the plan has been an effective tool. Highlighting the University of Iowa Libraries' plan, this article discusses a variety of subjects that should be addressed when preparing, writing, and implementing a plan for distance-education services.
