About

The Max Planck Encyclopedias of International Law is a comprehensive, analytical resource containing peer-reviewed articles on every aspect of international law. This definitive reference work contains both the Max Planck Encyclopedia of Public International Law and the Max Planck Encyclopedia of International Procedural Law.

Max Planck Encyclopedia of Public International Law (MPEPIL)

The definitive reference work on public international law

General Editor: Rüdiger Wolfrum, Director at the Max Planck Foundation for International Peace and the Rule of Law; former Director at the Max Planck Institute for Comparative Public Law and International Law

This major online reference work contains 1,700+ peer-reviewed articles on every aspect of the substance of international law. Written by an incomparable team of over 900 scholars and practitioners led by Professor Rüdiger Wolfrum, this comprehensive resource is essential for anyone researching or teaching international law.

Max Planck Encyclopedia of International Procedural Law (MPEiPro)

The home of international law in practice

General Editor: Hélène Ruiz Fabri, Director of the Max Planck Institute Luxembourg for Procedural Law

The Max Planck Encyclopedia of International Procedural Law (MPEiPro) maps and analyzes the systems and processes through which international law is made and adjudicated in practice. Each article is commissioned by General Editor Professor Hélène Ruiz Fabri and a team of experts at the Max Planck Institute Luxembourg for Procedural Law, providing cutting-edge and rigorously peer-reviewed research on areas of international law that are often under-explored. MPEiPro will take a broad view of international procedure, examining it from three different angles: technical points of procedure within specific institutions or across similar organizations; comparative accounts of families of institutions within specific subject areas or with similar functions; and theoretical, interdisciplinary entries.

The scope of the Encyclopedia mirrors the broad understanding of procedure underlying it, encompassing decision-making by international organs in general, including political and administrative bodies. At launch, the Encyclopedia will cover dispute settlement and adjudication. Coverage of non-adjudicatory modes of dispute settlement such as negotiation, mediation, and conciliation, as well as international political and administrative procedures, will be added over time. The Encyclopedia will eventually contain over 1500 entries.
