National Center for Policy Analysis
This think thank, which "seeks innovative private-sector
solutions to public policy problems," organizes its information here
in multiple ways. This includes "Policy Issues" on many different
topics, their "Policy Digest" (from a variety of sources, and
updated daily), its "Executive Alert," material for high school
debaters, and issues before Congress, and a special section on
global warming.
