Claims vs. Facts Database - Center for American Progress
"The Center for American Progress has launched this new database project to chart conservatives' dishonesty and compare it with the truth. In this database, each conservative quote will be matched against well-documented facts, so that users can get a more accurate picture of the issues. And we need your help. If we're missing a lie or distortion you know of, please submit an entry. If it checks out, we will gladly add it to the database."
