Recently HeinOnline has added the Law Library of Congress Reports to its online databases offerings. From Hein’s website:
The Law Library of Congress was established in 1832 as a separate department of the Library of Congress. Its mission 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, including one of the world’s best rare law book collections and the most complete collection of foreign legal gazettes in the U.S.
The Law Library produces reports on foreign, comparative, and international law in response to requests from Members of Congress, Congressional staff and committees, the federal courts, executive branch agencies, and others.
This database includes more than 3,500 reports from the Law Library of Congress on foreign, comparative, and international law—all in one easy-to-navigate collection. HeinOnline offer a helpful LibGuide which can help you explore the content further, and you can access the database itself via the Library Databases pages.
