I'm not sure whether its the same (or a related) site, but I was cleaning out some stuff on my machine about a week ago and "canned" a post - for when I found a good place to put it. What I found looked like some very helpful aids for teachers, some general information on searching the web, and some new stuff on copyrights.

The kid's song thing you're discussing may be somewhere on the same site(?)

Following was prepared a couple of weeks ago:

Cleaning out my "Favorites" list, and checking out some "obscure" references, I found an apparent bundle of "goodies" that my be of interest to any of us who need better search abilities, and particularly to any who might use, or want to use, web resources in Teaching or Libraries.

ERIC Clearinghouse on Information and Technology, sponsored byr US Department of Education (http://www.ericit.org/index.shtml).

For the items that took me there, look in the left column under BOOKS, and click "ERIC Digests."

Of particular note are two digest articles under "2001 Digests:"
Uncovering the Hidden Web, Part I: Finding What the Search Engines Don't (PDF)
Uncovering the Hidden Web, Part II: Resources for Your Classroom (PDF)

A couple of year 2000 items may still be of use for K-12 teachers:
An Introduction to Internet Resources for K-12 Educators, Part I: Information Resources, Update 2000
An Introduction to Internet Resources for K-12 Educators, Part II: Question Answering, Electronic Discussion Groups, Newsgroups, Update 2000

I had to poke around a bit to find that "ERIC" stands for "Educational Resources Information Center (ERIC)."

This is a Federally funded (US) site, apparently with all materials prepared under government funding, so there are no restrictions on copying or reproducing anything (that I saw). The "IT Digests" are specifically declared as "In the Public Domain."

If this is the same site, perhaps some of the "upstairs" stuff I was into will help clarify what's being changed - or not????
