The Law Library is the smallest of the seven departments of the Library of Congress, but it is by far the oldest, antedating any of the others by a good half century. It has the largest collection of legal materials of any institution in the world, and it not only covers the full story of U.S. jurisprudence (captured as it all happened), but its strength in foreign law is so great that its reputation is enhanced by its nondomestic holdings and staff.
