A thesaurus is an alphabetical listing of all the subject terms in a single database, used to classify and organize information for that database.

ProQuest Parliamentary Papers have an associated thesaurus (also called a controlled vocabulary of subject terms).  Editors use the thesauri to assign subject headings to documents in the database.

Using a thesaurus with your search

On the Basic and Advanced Search Forms, click the Find Terms link located below (on the Basic Form) or on the right (in the Advanced Form) of the search box.  A popup window opens, providing a list of the thesauri terms available. 

Click the checkbox and paste the term into the search box in the search form by using the "Paste to Search" button. Multiple terms can be selected.
