Links to Third Party Resources
This website contains links to external, third party resources (websites, images, pdf-files and other files). At the time of linking these resources, I have taken utmost care
- to check that the links work,
- that the content is genuine, and
- that the content does not contain any offensive material.
However, these resources are not under my control and I do not have the resources to permamently keep track of all changes.
Since I am concerned about the integrity and security of this website, I would appreciate it, if you immediately contact me in case of problems with these links (unwanted or offensive content, broken links etc.). I will then fix or remove the respective link as soon as possible.
