The Baltic Yearbook of International Law is an annual publication containing contributions on topical issues in international law and related fields that are relevant to Baltic affairs and beyond. In addition to articles on different aspects of international law, each Yearbook focuses on a theme with particular importance to the development of international law or interest to the Baltic region. Volume 11 of the Baltic Yearbook of International Law is the first volume devoted exclusively to one of the Baltic national schools of international law. Its theme is the Lithuanian school of international law and its traditions and modern developments. It is not often that contributions to the development and thought in international law from small States and academic communities achieve wider audiences or have larger influence. The Baltic Yearbook continues to serve as a forum for providing insights into international law scholarly debates and practices in the region. Like all the previous volumes, current volume contains extensive reports on practices of Estonia, Latvia and Lithuania in international law. The Yearbook thereby aims to contribute to the development of thought and relevant practices in the world.
