International law spans the globe and, per definition, concerns peoples and nations around the world. Yet, truly transboundary scholarly communication all too often is hampered by legal and technical barriers and obstacles. To overcome some of these hurdles, we are creating the first-ever Open Access textbook in international law in the context of the initiative “OpenRewi”. Read more.

OpenRewi – Open Legal Science was founded in 2020. “Rewi” is short for “Rechtswissenschaft”, the German word for legal science or legal scholarship. The aim of the initiative is to create freely accessible and usable teaching materials according to the Open Definition. In doing so, we strive for high content quality and up-to-date materials. We carry out the work on the individual publication projects in a decentralized, autonomous, and cooperative manner. Read more.

We are happy about everyone who wants to collaborate. There are many ways you can get involved. If you are unsure or have completely new ideas, just write to kontakt@openrewi.org. Read more.


International law spans the globe and, per definition, concerns peoples and nations around the world. Yet, truly transboundary scholarly communication is all too often hampered by legal and technical barriers and obstacles.

The Public International Law project is currently in its second writing phase. The first outcomes and the encouraging feedback both from within and outside the OpenRewi community help us stay motivated. In this post we provide a glimpse at the current version of the book outline and of individual chapters. Read more.
