(As far as I know, there are no browsers in use that can't recognize image mapping, but the interent is a big place . . .) It is likely that moderately old browsers will not recognize significant interactive features of this site. These significant features include quiz programs (JavaScript),  bibliography sort/call programs (Javascript), mine cost illustrations (Java applet) and suggestion links (javascript). Although the sugestion link can be bypassed to contact the webmaster directly via a mail link on  <a href="i_main.htm">i_main.htm</a>., there are no substitutions for these other interactive functions. <br>
