A change to the menu

The change over to the new server is now complete. Most visitors should not have noticed anything. If you link to my site you should note that the file extensions of all pages containing bibliographies have changed from .html to .php. - i.e. tertullian.html is now tertullian.php. You should be forwarded automatically to the new page in any case. Pages hosting articles or books and the main index page have not changed. Please update your links as necessary.

The change over has allowed me to drop the drop-down menus in favour of ones that use cascading style sheets. In my tests the pages loaded at least five times faster with the new menus, so visitors should find this helpful.
