This unique website explores the "diversity of the various legal systems, their languages and their economic and demographic importance in the world." A major aspect of the site is a map that shows the different types of law that govern the countries of the world. Across the top of the map are links to explanations of the different types of law, as well as which countries have a combination of laws or a unified system of laws. The types of law represented on the map are "Civil Law", "Common Law", "Muslim Law", "Customary Law", and "Mixed Systems". The "Demographic Distribution" link on the left hand side menu illustrates with graphs and tables the percentage in which the world population is represented by the various legal systems.
The following are guides to sources.
