"PolitiFact is a fact-checking website that rates the accuracy of claims by elected officials and others who speak up in American politics. PolitiFact is run by editors and reporters from the Tampa Bay Times, an independent newspaper in Florida, as is PunditFact, a site devoted to fact-checking pundits. The PolitiFact state sites are run by news organizations that have partnered with the Times. The state sites and PunditFact follow the same principles as the national site.
PolitiFact staffers research statements and rate their accuracy on the Truth-O-Meter, from True to False. The most ridiculous falsehoods get the lowest rating, Pants on Fire."
"We are a nonpartisan, nonprofit “consumer advocate” for voters that aims to reduce the level of deception and confusion in U.S. politics. We monitor the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases. Our goal is to apply the best practices of both journalism and scholarship, and to increase public knowledge and understanding.
FactCheck.org is a project of the Annenberg Public Policy Center of the University of Pennsylvania. The APPC was established by publisher and philanthropist Walter Annenberg to create a community of scholars within the University of Pennsylvania that would address public policy issues at the local, state and federal levels."
FAIR: Fairness & Accuracy in Reporting
"FAIR, the national media watch group, has been offering well-documented criticism of media bias and censorship since 1986. We work to invigorate the First Amendment by advocating for greater diversity in the press and by scrutinizing media practices that marginalize public interest, minority and dissenting viewpoints. As an anti-censorship organization, we expose neglected news stories and defend working journalists when they are muzzled. As a progressive group, FAIR believes that structural reform is ultimately needed to break up the dominant media conglomerates, establish independent public broadcasting and promote strong non-profit sources of information.
Uniquely, FAIR works with both activists and journalists. We maintain a regular dialogue with reporters at news outlets across the country, providing constructive critiques when called for and applauding exceptional, hard-hitting journalism. We also encourage the public to contact media with their concerns, to become media activists rather than passive consumers of news."
"We pursue our mission largely through our award-winning website, OpenSecrets.org, which is the most comprehensive resource for federal campaign contributions, lobbying data and analysis available anywhere. And for other organizations and news media, the Center's exclusive data powers their online features tracking money in politics - counting cash to make change. Our OpenSecrets Blog features newsbreaking original reporting about money-in-politics, including the sort of investigative work that won the Society of Professional Journalists' 2013 award for Public Service in Online Journalism."
"the definitive Internet reference source for urban legends, folklore, myths, rumors, and misinformation."
Wikipedia
Search for the name of the site. Wikipedia should give you a brief overview of a site or company if you are unfamiliar with them.

Three strategies separate checkers from the rest of us:
• Landing on an unfamiliar site, the first thing checkers did was to leave it. If undergraduates read vertically, evaluating online articles as if they were printed news stories, fact-checkers read laterally, jumping off the original page, opening up a new tab, Googling the name of the organization or its president. Dropped in the middle of a forest, hikers know they can't divine their way out by looking at the ground. They use a compass. Similarly, fact-checkers use the vast resources of the Internet to determine where information is coming from before they read it.
• Second, fact-checkers know it's not about "About." They don't evaluate a site based solely on the description it provides about itself. If a site can masquerade as a nonpartisan think tank when funded by corporate interests and created by a Washington public relations firm, it can surely pull the wool over our eyes with a concocted "About" page.
• Third, fact-checkers look past the order of search results. Instead of trusting Google to sort pages by reliability (which reveals a fundamental misunderstanding of how Google works), the checkers mined URLs and abstracts for clues. They regularly scrolled down to the bottom of the search results page in their quest to make an informed decision about where to click first.
