My website contains so-called “external links” (links to third party sites). I have no control of their content and I assume no liability for this reason. For the content and accuracy of the information the provider of information of the linked website is liable.

I am not liable for the content of the linked sites and dissociate myself preventive from those sites:

With the finding from Landgericht Hamburg on 12 May 1998, the court decided, that by setting a link to third party site if applicable one is liable for thier content. This can be avoided – as the court states – only by explicit dissociation from those contents. I have set links on several sites on this homepage to third party websites. For all those links applies: I explicitely point out, that I have no influence on the design ans content of the linked websites. Hence I dissociate explicitly from all contents on the linked websites. This statement applies on all external links on my homepage.
