Resource Discovery Network:
April 17th, 2002
“The Resource Discovery Network is a free Internet service dedicated to providing effective access to high quality Internet resources for the learning, teaching and research community.” [Link via Online Learning Daily] Another resource that’s directed more at K12 (and, unfortunately, not free) is NetTrekker, which has teachers index and summarize educationally useful websites, ranks them, and cross-reference them by state educational standards.
