Referrals and links

The Author is not responsible for any contents linked or referred to from his pages – unless he has full knowledge of illegal contents and would be able to prevent the visitors to his site from viewing those pages. If any damage occurs by the use of information presented there, only the author of the respective pages might be liable, not the one who has linked to these pages. Furthermore the author is not liable for any postings or messages published by users of discussion boards, guest-books or mailing lists provided on his page.


The author intended not to use any copyrighted material for the publication or, should this be unavoidable, to indicate the copyright of the respective object. Sound recordings, video sequences, graphics and texts can only be drawn on if these are not protected by copyright. If you find any unindicated object protected by copyright, the copyright could not be determined by the author. In the case of such an unintentional copyright violation the author will remove the object from the publication or at least indicate it with the appropriate copyright after notification. The copyright for any material created by the author is reserved. Any duplication or use of such diagrams, sounds or texts in other electronic or printed publications is not permitted without the author´s agreement.
