Law Guide

At the EUI Library, we use the Dewey Decimal Classification (DDC) system to organize materials across all disciplines, including Law.

Understanding how law books are classified can help you navigate the shelves and the catalogue more effectively.

All Law print books are classified within the 340s. This section includes everything from general legal theory to national and international legal systems.
