A project of the Annenberg Public Policy Center of the University of Pennsylvania, factcheck.org reports on the accuracy of "what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases."
Politifact
PolitiFact started in 2007 as an election-year project of the Tampa Bay Times (then named the St. Petersburg Times), focused on looking at specific statements made by politicians and rating them for accuracy.
Media Bias/Fact Check
A volunteer run site that evaluates news sources for bias and factual accuracy. A detailed "Methodology" section explains the process the MBFC uses. (It's also a useful read if you, dear librarian, could use a refresher on vetting sources.)
