Find Bills by Subject and Policy Area
Legislative analysts from the Congressional Research Service (CRS) closely examine the content of each bill and resolution to assign Policy Area Terms and Legislative Subject Terms. The Legislative Indexing Vocabulary (LIV) is an older CRS thesaurus that was discontinued in 2008. Terms from all three subject vocabularies can be used to enhance Congress.gov research. Terms assigned to a bill can be seen from the "View subjects" link to the right of each bill's overview. Terms are assigned to bills and resolutions, but not to amendments.
|Vocabulary||Number of Terms||Number of Terms per Bill||Coverage Dates|
|Legislative Indexing Vocabulary (LIV)||5,500||varies||1973-2008|
Using Policy Area Terms
1. The "Subject - Policy Area" filter can be selected from any search results list, including Legislation of the U.S. Congress and any Congressional member profile, to refine the list to only items in a selected policy area. The "Subject - Policy Area" filter lists most-used terms in descending order.
The policy area term vocabulary is consistently used for all bills and resolutions introduced since 1979 (96th Congress). The term Commemorations was used from 1997 to 2008 (105th-110th Congresses) to categorize measures introduced to honor or memorialize. The term displays in the Subject - Policy Area section of those measures. Examples: H.Con.Res.205 [110th]
4. Policy area terms may be used with the billPolicyArea search field from command line or the main search box. Copy the below example and paste it into a search box to see how this search works.
