Search+Sites

[|Internet Public Library] Super nice interface - limit by teens or kids, subject matter, etc... Plus, safer and more authoritative results than Google.

[|Dogpile] A bit more commercially oriented than even Google (Deal of the Day search, restaurant search, etc..) but it's a metadata site and works well for collaborative project research with images, videos, etc..

[|United States] Economics, Social Studies, Civil Service, Statistics, - more and more this site amazes me as a great search site for many subjects. Authoritative and trustworthy--yes, our US government.
