Thanks to Fred Sawyer and others I have enlarged my list of sundial links. You may access it under http://www.ph-cip.uni-koeln.de/~roth/slinks.html
It's just a simple text only page - so it will not take long time to transfer to you. I would like to bring some order into it. And if anyone has found a new gnomonic link, please mail it to me. - Daniel
