I just got back from Ann Arbor, MI after meeting and listening to Siva Vaidhyanathan talk at his book signing for "The Anarchist in the Library" at Shaman Drum Bookshop on State Street. I haven't had a chance to read it yet, but I'll post a review as soon as I get the chance.
The book reading was short and sweet with a small group and lots of questions. I enjoyed it tremendously and tried to record it but alas my recorder shut off about 15 minutes in. However, you can watch a similar speech he gave as part of the Luminary Lectures at the Library of Congress entitled The Anarchist in the Library: The Moral Panics over Copyright and Free Speech. It's an excellent speach.
