Max Planck Encyclopedia of Comparative Constitutional Law (MPECCoL)

On April 27, Oxford University Press launched the brand new Max Planck Encyclopedia of Comparative Constitutional Law (MPECCoL), a key research complement and application to the vast trove of primary constitutional texts and analytical commentary already available in the constitutional law family of products: Oxford Constitutions of the World and US Constitutional Law.

The encyclopedia articles—modeled on those in the Max Planck Encyclopedia of Public International Law—address a focused range of topics that seek to provide the best coverage of the essence, character, development, and history of constitutional law from a global perspective. The articles will define and cover the basis and foundations of state formation and constitutional law, as well as analyzing and explaining underlying legal concepts such as: human rights, constitutional formation, scope of state protections, the defining structures of governmental makeup, types of legal structures and interactions within a constitutional law system, and legal constitutional concepts that make up constitutional law.
