This Nutshell provides a basic introduction to international legal research for the non-specialist. It offers guidance through the unfamiliar pathways of research using international legal materials and demystifies the world of treaties. Since it's aimed at the non-specialist, it provides straight-forward background information on the United Nations and the European Union and includes guidance using the documents and legal materials of these institutions. There are extensive links to the rich world of Web resources, but it also describes paper research tools that remain important in this field. Finally, it sets out a road map for approaching an international legal research problem.
