At a recent appointment, I asked a question that my doctor could not answer, so he swivelled around to the computer in the examination room, typed in a few words, and almost instantly brought up all the literature that he needed to respond to my query. The ease with which my doctor accessed that information raised a question in my own mind about why our discipline has not organised our knowledge as effectively as medicine has done. Why can't we do key word searches and bring up the current research, the most relevant information, and the best ideas and applications in our field for us to assess and build upon? The answer, I think, has to do with our discipline lacking an effective knowledge loop.
