One thing I love about the web, even if you're avoiding work or killing time, you can't avoid running across useful web sites! Makes you want to find a quiet cabin off the grid .... but, never mind that! Here is what I found:
The Encyclopedia of Education Technology is a searchable and categorized list of topics pertaining to the intersection of technology and education. It is multimedia enhanced, written for educators, and contains references, suggested uses for technology and links for more information.
Frankly, it is awesome and looks like a wonderfully useful tool!
