A graphical site map is available and a text version is available on the search engines page. A "breadcrumb trail" at the top of each page allows easy navigation back up the web tree. Most links that leave the site open in a new window. The text at the bottom of each page shows when the page was last edited and names the main author of the information on the page.
Icons next to links give a graphical indication of the target destination:
= a "private area" link, password protected
= a CD-ROM link, available from the CD-ROM
= an internet link beyond this site, usually opens in a new window.
= a visited internet link
