Inter-University
Consortium for Political and Social Research (ICPSR)
ICPSR is the closest thing we have to a national data archive, though it contains
international data as well. If you are looking for social or political data,
it should be your first stop. It also contains some historical and economic
data as well.
If you haven't used ICPSR before, I recommend beginning with the Data
Use Tutorial.
