title: Constants, context, and change: the pursuit of purpose.
abstract: OBJECTIVE
  This lecture addresses the history and philosophy of librarianship, in general, and medical librarianship, in particular. The author discusses the profession and attempts to set its place in the context of the social and cultural worlds in which we function and in the context of the professions which we serve.
  
  
  CONCLUSIONS
  Goals are identified that are common and immutable. Examined are the changing methods by which we meet these ends, particularly the impact of technology and other factors on how we function now and in the future. Change itself is identified as the one constant of which we can be certain. That we strive and achieve is because of a sense of purpose that has guided so many of our profession's leaders. Acknowledging an embarrassment of riches, I point to the achievements of some of the most notable of my colleagues and friends, as examples of what such an extraordinary dedication to the pursuit of purpose makes possible.
  
  
  CONCLUSIONS
  So long as we maintain this pursuit of purpose, which is, as Estelle Brodman said of the pursuit of excellence, a statement of faith in ourselves, our future is secure.
