What are the functions of museums likely to be in the twenty-first century? One thing is certain. Museums must develop a clear social function. During the 1990s a new age has dawned, a knowledge-based age that will replace the post-industrial age that has existed for the last hundred and fifty years. As the heavy plant of industrial production is replaced by the micro-circuits of the computer, the emphasis changes from the production of technology to the production of ideas, the pace of knowledge transmission increases, and possibilities for intellectual action multiply. Knowledge races around the world in a micro-second, information is accessed in new ways, and new levels of interconnectivity become possible.
