Changes in the health information environment present a major challenge to health sciences librarians. To successfully meet this challenge, librarians must apply the concepts of informal, self-directed, lifelong learning to their own carers. The Joint Commission on Accreditation of Healthcare Organizations is creating an integrated information environment in health care organizations. The health sciences librarian brings unique knowledge and skills to this environment. The reference technique, a methodology that closely parallels other problem-solving approaches such as the physician's diagnostic technique, equips librarians with the conceptual skills to develop creative solutions to information management problems. Each health sciences librarian must assume responsibility for extending professional skills and abilities and demonstrating them in the workplace.
