| THOMAS Databases | How Often Is THOMAS Updated? | THOMAS Usage Statistics | About INQUERY |


Acting under the directive of the leadership of the 104th Congress to make Federal legislative information freely available to the Internet public, a Library of Congress programming team brought the THOMAS World-Wide-Web-based system online in January 1995, at the inception of the 104th Congress. The first database made available was Bill Text, followed shortly by Congressional Record Text, Bill Summary & Status, Hot Bills, the Congressional Record Index, and the Constitution. Enhancements in data and search and display capabilities have been continuously added for each database. The next major database to come up under THOMAS will be the full text of Committee reports.

HOW OFTEN IS THOMAS UPDATED?

As soon as new files are received from the Government Printing Office, they are indexed and made available for searching. The bill text files are updated several times throughout the day. The Congressional Record files are received once a day, when Congress is in session, usually in the morning.

Information about bills in the Bill Summary & Status files is made available one day after it is entered into the system. Depending on the amount of legislative activity, inputting of the legislative status may lag behind. Bill digests usually are available within 48 hours of the introduction of the bill; likewise, subject terms may take several days to be assigned to bills.

ABOUT INQUERY

Searching in THOMAS is done under the INQUERY information retrieval system, developed by the Center for Intelligent Information Retrieval based at the University of Massachusetts at Amherst.

INQUERY employs a relevance-ranking algorithm for searching, and displays search results with the most-relevant items appearing first on the results list. Experienced searchers who wish to use Boolean searching may use native INQUERY syntax to override the relevance-ranking default.
