Here's How - Open Access
It is not only professors from MIT and Stanford who are contributing to the Read/Write Web and taking the open access principle seriously.
Founded at Rice University, Connexions is a free global online education system that puts the power of creation and collaboration in the hands of teachers worldwide.
Connexions allows authors to upload bite-sized chunks of learning materials called "modules." Modules are pieced together to form whole courses, or "collections."
Anyone can build a collection from any combination of modules, and collections can be downloaded in PDF format, bound and printed at a fraction of traditional textbook prices.
