To all users
The pages are adjusted to a standard 15" or 17"monitors with a 800
x 600 or 1000 x 728 resolution . You should take care that a monospace font has
been installed on your browser since the reading of some tabels
may otherwise be very hard.
You will often have to use the back-button of your browser to
navigate, since several hyperlinks have often been addressed to
the same file so that no back-link was installed.
If you want to copy pictures for your own use you will have to click on them with the right button of your mouse. Should you find the transfer speed of the internet version to be insufficient than how about ordering the German version on CD ?
