The Duke Law & Technology Review has published a special issue: The Past and Future of The Internet: A Symposium for John Perry Barlow (entire issue file).
Here's an excerpt from the introduction by James Boyle:
John Perry Barlow passed away on Feb 7th, 2018. John Perry's name is generally followed by a long list of qualities: poet, lyricist, rancher, civil libertarian, co-founder of the Electronic Frontier Foundation, teller-of-stories, organizer of parties, bringer of light. Good friend. Certainly he was all of these. The picture above gives you some sense of his personality. But he was also the author of two influential essays in the very early days of the World Wide Web—A Declaration of the Independence of Cyberspace and Selling Wine Without Bottles: The Economy of Mind on the Global Net. . . .
Rather than offer a simple Festschrift for Barlow, this symposium uses those two essays as the jumping off point for a reflection on the current state of the digital world.
