The Open Source Principles Text - R. Preston McAfee

Quote: The publishers are vulnerable to an open source project: rather than criticize the text, we will be better off picking and choosing from a free set of materials. Many of us write our own notes for the course anyway and just assign a book to give the students an alternate approach. How much nicer if in addition that is free. Moreover, by doing it this way, we avoid the problem of assigning a $100 book that has all sorts of errors and problems, an assignment which justifiably annoys students. I'll start by contributing a version I am happy with and then collectively we can develop a set of readings and exercises that are tunable to distinct audiences (my contribution will be tuned to Caltech) and make a text superfluous.

Preston is a very creative man. It will be interesting to watch this project evolve.
