Sharing navigation and design similarities with the Library of Congress site as well as the U.S. National Archives and Records Administration site, today’s launch of the upgraded THOMAS Congressional information site offers citizens, educators and researchers additional browse and search features (including the ability to Search Multiple Congresses, from the 101 to the 109; links to full text treaties; and a Presidential nominations search feature with links to Senate hearings). This year was the twentieth anniversary of the site, which has undergone a series of changes, updates and redesigns.
