By 12 May 1998 the regional court Hamburg decided that one by placing a link to the contents of the linked site becomes responsible for it, too. This - according to the court - can only be prevented by explicitly distancing oneself from these contents. The operator of the site has placed on its pages links to other sites on the Internet. Therefore, the operator dissociates itself expressly from any content and sites linked to this Web Site, including all subpages. All pages are listed in the offer but quoted in the scientific and entertaining purposes and as information made available. We assume no liability for the content of external sites and distances ourselves from the content of the principle sources listed.
