The ResearchChannel Consortium

• An intellectual community, we make knowledge
  available to all by sharing our
  developments,insights and discoveries with a
  global audience.
• We bring together ideas from many of the worlds
  premier academic and research institutions and
  disseminate those ideas to the public
  directly,without interference.
• We are committed to technological innovation
  toenable leading-edge exchanges of our
  resources.
