              The NCI Term Browser home page lists alphabetically the 
              terminology sources that are available.  Click on a source 
              name to go to its home page, or click on a source's check 
              box to include it in a search from the NCI Term Browser 
              home page.  Below the sources list are three buttons:
              
              <ul>
                <li><b>Select All</b> includes all sources for searching, leaving their check boxes checked.</li>
                <li><b>Clear</b> unselects all sources, unchecking their check boxes.</li>
                <li><b>Search</b> starts a search in the same way as the Search button in the search box.</li>
              </ul>
              
              The <b>Sources</b> link at the top of the NCI Term Browser home page 
              gives information about all sources, including the source 
              descriptions appearing on each source's home page.
