The Library of Congress, in collaboration with the U.S. Senate, House of Representatives and the Government Printing Office (GPO), last week unveiled, a new public beta site for accessing free, fact-based legislative information. features platform mobility, comprehensive information retrieval, and user-friendly presentation., at, eventually will replace the public THOMAS system and the congressional Legislative Information System (LIS).

THOMAS, named for former President Jefferson, was launched by the Library in 1995 as a bipartisan initiative of Congress and averages 10 million visits each year. The system has been updated over the years, but the foundation can no longer support the capabilities that today’s Internet users have come to expect, including access on mobile devices.

Using best practices for retrieving and displaying information, the refined, user-friendly system also will make finding and using legislative information more intuitive, comprehensive and accessible than the existing system. connects the information with a title and URL more readily identified by all constituencies. The site includes bill status and summary, bill text and member profiles and the following new features:

  • Effective display on mobile devices;
  • Ability to narrow and refine search results;
  • Ability to simultaneously search all content across all available years, with some files dating from the 93rd congress;
  • Easier identification of current bill status;
  • Members’ legislative history and biographical profiles; and,
  • Maintenance of existing features such as links to video of the House and Senate floor, top searched bills and the save/share feature.


The Library is releasing as a beta site to enable a period of time for collecting user feedback and refining functionality while other content is incorporated. Other data, such as the Congressional Record, committee reports, nominations, treaties and communications, will be incorporated over time in a planned, prioritized order. The Library anticipates will operate as a beta site for approximately one year as this work is completed. During that time, both THOMAS and LIS will continue to operate as usual.
