Research Center Law Library of Congress

About the Law Library

The mission of the Law Library of Congress is to provide authoritative legal research, reference and instruction services, and access to an unrivaled collection of U.S., foreign, comparative, and international law. To accomplish this mission, the Law Library has assembled a staff of experienced foreign and U.S. trained legal specialists and law librarians, and has amassed the world's largest collection of law books and other legal resources from all countries, now comprising more than 2.9 million items.

Appointments are optional, but encouraged. To help us better serve you, request a research appointment to ensure collection material is accessible during your visit to the Library.

The Library of Congress asks all visitors to follow our COVID-19 health screening protocols, which are based on guidance from the Centers for Disease Control and the Office of the Attending Physician of the U.S. Capitol.
