The search site Court Listener was created by a masters student at the Berkeley School of Information, with the goal of creating a free and competitive real-time alert tool for the U.S. judicial system.  Right now, the site has daily information on all precedential opinions issued by the 13 federal circuits and the Supreme Court was started back in 1991 by two international trade lawyers, and it contains two parts. The first part is free to all visitors, and features primary source documents on international trade law, a search engine for GATT/WTO opinions, links to other international trade law sources, and a discussion forum. There’s also a subscription service
