There are tools and then there are tools. Resource that are free for all (for now). The mind boggles. Some cases in point:

The Internet Archive

  The best media resource for me - ever!  And the "Way Back Machine"!

Open Culture

  Wonderful free cultural and educational media on the web

The Wikimedia movement

  Just a few of:
  * Wikipedia
