Free textbooks for everyone—that’s the goal of the Global Text Project, an initiative spearheaded by Rick Watson, a professor in the University of Georgia Terry College of Business. Watson’s goal is to produce a library of 1,000 textbooks that will be created with wiki technology and will be made available to students around the world.Inspiration for the project came from a course Watson taught in 2004. He was unable to find a suitable text for a graduate-level XML course, and so he designed a course where the students wrote a textbook of their own.
