Planning is an ongoing process. No plan is perfect, and inevitably planners neglect to include important details. A planner requires personal attributes such as managerial skills, awareness of the risks to his or her library, and persistence. There is no better test for a plan than an actual disaster. A case history shows how a public library resumed operations after a fire. The head librarian notes the lessons that she learned during the resumption process. If the goal is the survival of libraries, then librarians need disaster plans.
