Flat World Knowledge

Flat World Knowledge is a publisher of college-level textbooks and educational supplements founded in 2007 by Eric Frank and Jeff Shelstad. Its company headquarters are in Washington, DC. The company originally offered every textbook published for free using online delivery under the open content paradigm, but in November 2012, the company announced that it will no longer offer a free version citing financial concerns as the reason for the change. Educator teaching supplements and materials consistent with industry norms are available at no charge.
