1. Content of the material on-line
The authors of this website does not warrant that the information it contains is up-to-date, correct or complete. Liability claims against the author in respect of material or immaterial damages caused by the use or non-use of the information provided and/or the use of inaccurate or incomplete information are excluded on principle unless there is proof of intention or gross negligence on the part of the author. All offers are non-binding and subject to change. The authors expressly reserves the right to change, add to or delete portions of pages or the entire contents without separate notification and/or to temporarily or permanently discontinue publication.

2. References and Links
With respect to direct or indirect links (“hyperlinks”) to websites that lie outside of the authors’ sphere of responsibility, the authors are liable for content only to the extent that they are aware of the content and that it would be technically feasible and reasonable for them to prevent the use of any illegal content. Otherwise, liability for the content and, in particular, for damages arising out of the use or non-use of provided information of that type extends only in the case of the providers of linked sites, not persons who only make reference to the individual publications over links. This restriction also applies to all entries by third parties in guest books, discussion forums and mailing lists set up by the authors.

3. Copyright
In all publications, the authors endeavour to honour the copyright of any graphics, sounds and texts used, to use graphics, sound recordings, video sequences and texts that they have produced themselves or to make use of graphics, sounds and texts that are not subject to licence. Should, in spite of these efforts, an unidentified graphic, sound recording, video sequence or text that is protected by a third-party copyright appear in a publication, the authors were unable to determine the copyright. In the event of unintentional breach of copyright of this kind, the authors will remove the relevant item from his publication upon notification and/or identify it using the appropriate copyright. The copyright for published items created by the authors themselves is retained solely by the authors of the pages. Reproduction or use of such graphics, sounds or texts in other electronic or printed publications without the express permission of the authors is prohibited.
