Foreign and Comparative Law Research Guide

  • Foreign law is the domestic law of a country other than the United States. Comparative law is the study of domestic law between or among individual countries. (Treaties and other international agreements fall under International Law). 
  • Know what type of legal system(s) pertains to your country (civil law, common law, mixed jurisdiction, etc). See, World Legal Systems or Legal Traditions of the World: Sustainable Diversity in Law (K559 .G545X 2010 - there are also 2007, 2004, and 2000 editions of this book available). 
  • Caveats:
      • There may not be published sources of law for a particular country.
      • If there are, the sources may not be in English.
      • If sources are available in English, Yale Law Library may not have them (but we probably do!).
      • If they exist in our collection, they may not be current, or the translations may not be accurate.
  • Yale’s F/I webpage – This is an evolving consolidation of F/I electronic resources, primary and secondary sources, subscription and open access.
  • Several databases require a password; passwords can be found on your Inside home page under your Research Sites.

Bibliography on foreign and comparative law : books and articles in English
Compiled and annotated by Charles Szladits.
Elgar Encyclopedia of Comparative Law
This encyclopedia on comparative law is intended by editor Smits (European private law, Maastricht U., the Netherlands) to be a reference work that will allow a general readership to take stock of the field in its current state. Thirty-seven entries explore specific areas of the law, including criminal law, administrative law, insolvency law, et cetera. Twelve are dedicated to analysis of methodological questions in comparative law, such as the aims of comparative law, the idea of a European Civil Code, and legal transplants. Relatively substantial entries examine common law and the legal systems of the US, Germany, Japan, Scotland, and Russia, so chosen because of their importance in recent comparative law debates.

This three-volume encyclopedia, put together by Robbers (law, Institute for European Constitutional Law, U. of Trier, Germany), is essentially a comparative introduction to the political constitutions of the world's countries, from Afghanistan to Zimbabwe.
