Faced with the challenge of keeping up with the rapidly changing field of information systems, author and teacher John Gallaugher opted to write an open source textbook with a new online company, Flat World Knowledge (FWK). Gallaugher's open source textbook, "Information Systems: A Manager's Guide to Harnessing Technology", has an expected publication date of summer 2009. Yet, he is publishing chapters and case drafts online as they are ready for release. About 40 percent of the book was online by September, and the material was already being used by faculty worldwide. He states that for teachers and students, open source textbooks provide fresh, current and engaging content. Furthermore, the FWK format brings free, online content accessible from anywhere. He has found many benefits in FWK's model, including: (1) Retention of the copyright of his material; (2) Fast production cycles allow him to get content to consumers quickly; (3) The ability to provide a free online version of the product; and (4) Low-cost print versions.
