              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 four buttons:
  
              <ul>
                <li><b>Select All</b> includes all sources for searching, leaving their check boxes checked.</li>
                <li><b>All but NCIm</b> includes all sources except NCI Metathesaurus (NCIm), as searches with thousands of hits may be slow when NCIm is included.</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.
