Islands and their status in international law have become one of the more contentious issues in public international law.

Written by one of the world's leading public international lawyers, it offers an authoritative overview of how public international law operates in relation to islands. Key issues such as artificial islands, archipelagos, sovereignty, territorial rights, maritime entitlements, and governance are explored in depth. This will become a classic text in the field of international law.
