As regards direct or indirect references to external websites (“hyperlinks”) which are outside the area of responsibility of the author, liability would only be assumed if the author had knowledge of content and if it was technically possible and feasible to prevent their use in case of illegal content.
The author has no influence whatsoever on the current and future design, contents and authorship of the linked / referenced pages. For this reason, the author expressly dissociates himself from the contents of all linked / referenced pages which were changed after the links were first established. This statement applies to all links and references set up within the author’s own website as well. Only the provider of the page to which reference was made shall be liable for illegal, incorrect or incomplete contents and notably for damage resulting from the use of or failure to use such information provided, but not the person who merely refers to the publication in question via links
