THOMAS was the first online database of United States Congress legislative information. A project of the Library of Congress, it was launched in January 1995 at the inception of the 104th Congress and retired on July 5, 2016; it has been superseded by Congress.gov.
The resource was a comprehensive, Internet-accessible source of information on the activities of Congress, including:
- bills and resolutions
- summaries and status
- voting results, including how individual members voted
- Congressional Record, including the daily digest
- presidential nominations
The database was named after Thomas Jefferson, who was the third President of the United States. According to some sources, "THOMAS" is an acronym for "The House [of Representatives] Open Multimedia Access System", but as of November 2006 this text was not apparent anywhere on its site; this explanation might be a backronym.
