"Crowdsourcing" a Textbook

Imagine a world without books ... well, that is not far away. The Huffington Post reports Borders, the one time superstore of textbooks will be filing for bankruptcy as soon as this week. It's stock closed today at $0.23 per share. How about a world without a textbook. Okay not really, let's say without paper textbooks? Professors at North Carolina State University are experimenting the concept of student-authored wiki textbooks. The professor posts the topic and the students contribute through managed wikis, blogs, et all the ceteras. So far, thay have one "textbook" with 40 sections writtn by more than 120 students.
