Content: Selected Essays on Technology, Creativity, Copyright, and the Future of the Future (Facebook link)
A compilation of Cory Doctorow penned essays focusing on Copyright, DRM, and technology. Some of the older works (from 2+ years ago) are showing their age. For example, he takes shots at the failures of Amazon's Kindle (1st version) which, at least in part, ring hollow with Kindle 2's release.
A lighter, and slightly more reactionary view of copyright than what is found in Lawrence Lessig's Remix and James Boyle's The Public Domain, it's still full of style and insight. Of the three, I recommend Remix the most strongly, though all three books shed different light on the same subject.
If you find application of copyright in the digital world interesting, like me, or enjoy Doctorow's writing on sites like Boing Boing, also like me, you'll probably get a lot out of Content.
