Open access to international business law
A curated, freely accessible collection of literature, case law, and resources on international business law. Continuously updated, suggestions welcome.

Anyone who works closely with international business law, in practice or research, knows that legal research often takes a lot of time and money.
Fortunately, more and more good literature and resources are now freely available.
That is why I have started collecting freely available sources on international business law. This overview is a first stop for research and open to everyone. I keep adding sources and welcome suggestions for more open-access material.
