As an Audible subscriber I was able to download Anderson's latest Free: The Future of a Radical Price for zero dollars and zero cents (and 0 credits).
The same book in abridged format is $13.22 or 1 credit (as abridging is expensive).
On Amazon the price is $17.19.
Gladwell as a provocative (and I think somewhat wrong-headed) review in the New Yorker.
I'm sure we will have a lively discussion about where "free" and "open" come together. Many of us on campus have become big believers in giving away on the Web as much as what happens on campus as possible. We want to publish and share our lectures, our talks, our articles, dissertations, learning objects, data sets, training materials etc. etc.
Where ever you fall on Anderson's central thesis, you have to admire his willingness to put his money where his mouth is and give away the digital audio version for (about) the cost of the raw materials.
What are you waiting for....go and get your book!
