Congress.gov is the official source for federal legislative information. It replaces the nearly 20-year-old THOMAS.gov site with a system. It currently includes all data sets available on THOMAS.gov except nominations, treaties and communications. These data sets will be added throughout 2014. Until that time they are still accessible through THOMAS.gov via the link below. THOMAS.gov will be permanently retired by the end of 2014.
