Max Planck Encyclopedia of Public International Law Online (MPEPIL)

Max Planck Encyclopedia of Public International Law Online (MPEPIL, has just launched as Oxford University Press’s newest online product. This monumental reference work, originally published in 1991, has been fully updated and released in an easy-to-navigate online environment.

Developed in partnership with the Max Planck Institute of Comparative Public and International Law, this online service contains over 450 articles including more than 700 new topics not covered in the previous print edition. New material will be added quarterly until all of the nearly 1700 articles are made available by 2010.

  • Innovative functionality allows users to browse content alphabetically, by subject and author, or via quick and advanced search functions
  • Increased coverage of international criminal law, international dispute settlement, trade law, and environmental law reflect modern developments in the practice and study of public international law
  • All articles undergo rigorous evaluation by an Advisory Board consisting of renowned experts in various fields of international law, and internal advisors who are Senior Research Fellows at the Max Planck Institute to ensure the highest quality of scholarship
  • All articles include links to the Oxford Law Citator, which provides subscribers with easy-access linking to related articles in MPEPIL, as well as content from all other new law online services from OUP.

Detlev Vagts, from the American Journal of International Law, praised the hardcover versions of Max Planck as being “a monument of learning,” and Thomas Walde of ICLQ called it “an instrument that any serious library, university, foreign affairs ministry, international organization or law…should have.”

As the definitive reference work on public international law, MPEPIL is truly a powerful tool that all researchers and practitioners can benefit from.
