Ok, sorry to belabor this. Earlier today, I mentioned that you could download the audiobook of Chris Anderson's Free: The Future of a Radical Price at Audible for no cost. It turns out that the Audible offer isn't available to a worldwide audience. It may just be available to US residents. The good news is that I pinged Chris Anderson on Twitter, and asked if there's a universal version out there. And he kindly pointed me in the right direction. Here's the deal: you can get a universally free version over on Wired's website. The page is here, and the zip file is here. Hope that helps.
Note: I've added Anderson's zip file to our collection of Free Audio Books. There, I've also recently added a couple of related works: Lawrence Lessig’s Free Culture and Cory Doctorow's Content: Selected Essays on Technology, Creativity, Copyright and the Future of the Future . You can find them housed under Non-Fiction.
