College students living at or below the poverty line often have difficult choices to make: buy groceries, pay rent, or purchase textbooks. To Eric Frank, cofounder of Flat World Knowledge, this is not really a choice. When it comes to eating or buying a textbook, most will choose to eat. According to Frank, the biggest barrier to learning on scale is access to information. But Frank is optimistic that his new textbook publishing model will eliminate barriers that prevent economically disadvantaged students from accessing information and continuing their education. Frank's company, Flat World Knowledge, publishes open-licensed textbooks. His model not only allows college professors to choose the book they prefer for their courses, it also allows students to choose the price and the format of the book. What makes Flat World textbooks open-licensed is a set of rights that allow an individual professor to improve upon the book for his or her class.
