ASIL Electronic Research GuidesThe Electronic Resource Guide, often called the ERG, has been published online by ASIL since 1997. Systematically updated and continuously expanded, the ERG is designed to be used by students, teachers, practitioners, and researchers as a self-guided tour of relevant, quality, up-to-date online resources covering important areas of international law. The ERG also serves as a ready-made teaching tool at graduate and undergraduate levels.
