SourceWatch is a collaborative project of the Center for Media and Democracy (http://www.prwatch.org) to produce a directory of the people, organizations and issues shaping the public agenda. SourceWatch’s primary focus is on documenting public relations firms, think tanks, industry-funded organizations and industry-friendly experts that work to influence public opinion and public policy on behalf of corporations, governments and special interests. Over time, SourceWatch has broadened to include others involved in public debates including media outlets, journalists and government agencies. Unlike some other wikis, SourceWatch has a policy of strict referencing, and is overseen by a paid editor. This has been added to Research Resources Subject Tracer™ Information blog.
