an example would be the M$ website... simply type www.microsoft.com/robots.txt
they are all very similar throughout most domains, however you can learn quite a bit from some...an example would be here at webmasterworld.com quite a few disallowed robots within their robots.txt
the file itself is place in the root of the domain (IE same place your index.html, etc is placed)
hope that helps
