The featured research center on the Library of Congress Today is the Law Library of Congress. It is worth noting this especially useful collection and the expertise of the professionals who work there: “The mission of the Law Library is to provide research and legal information to the U.S. Congress, U.S. Federal Courts and Executive Agencies, and to offer reference services to the public. It contains the world’s largest collection of law books and other resources from all countries and provides digitized information with online databases and guides to legal information worldwide.”
