Through technical changes, the link structures on my website have changed. I have as far as possible informed people who have linked to me on their websites. If I forgot someone, please excuse that.
Please search here for the title of the article you had linked to, and then you will find the link in the address bar of your browser, or you move the mouse over the title and copy the link.
The links of my articles and pages to the original german versions will be updated gradually.
