The Electronic Information System for International Law (EISIL) launched in September 2004. Developed by the American Society of International Law (ASIL), a scholarly association that has been a leader in the analysis, dissemination and development of international law since 1906, EISIL is an open database of authenticated primary and other materials across the breadth of international law, which until now have been scattered in libraries, archives and specialized web sites. This huge catalogue provides bibliographic information on legal citations, entry into force and signature dates, amendments and brief descriptions, plus, of course, direct links to the web resources.
