As you have been learning, the American legal system is only one of hundreds in the world. Each of those legal systems has its own rules, sources, and authorities. But these systems do not exist in a vacuum. What rules govern when two or more States or entities interact? What are the enforcement mechanisms? The study of these questions comprises the fields of foreign law and international law. The purpose of this chapter is not to give you a comprehensive review of all the resources available for researching this vast field of law. Rather, the goal is to give you enough of an overview to get you pointed in the right direction when faced with an issue of foreign or international law.
