Two electronic sources that I use to keep up to date on internet law:
1. The SSRN Cyberspace Law online journal edited by Lawrence Lessig of Stanford and Peter Swire of Ohio State can be set up to email you regular updates, and currently contains over 1600 scholarly law articles on the topic. You must be registered with SSRN and log in to see the articles.
2. The Internet Law News from BNA, compiled by Professor Michael Geist, is a free daily e-mail summary of developments in Internet law with links to full text. It's easy to set up a daily email.
