Wayback Machine: Sweet research tool

I just found the coolest web research tool - the Wayback Machine at archive.org.

Ok, ok, I didn't "find" it. I heard it on NPR. But still, it is a wealth of knowledge for those who don't think the web has enough information. Now you can go back in time and discover obsolete information!

Stay tuned for an impromptu research demonstration, brought to you by the Emissary.
