1. Content of the online offer 

The author assumes no responsibility for the up-to-dateness, correctness, completeness or quality of the provided information. Liability claims against the author, which allude to either material or ideational claims that have occurred because of the utilization or non-utilization of the provided information or because of the utilization of incorrect and incomplete information are strictly ruled out, provided that no demonstrable voluntary or wantonly negligent default of the author is existent. All offers are subject to confirmation and without engagement. The author serves the right to change part of the web site or the whole offer without announcement, to add or to cancel information, or to cease the publication temporarily or definitely. 

2. Cross references and links 

In the case of direct or indirect links to other web sites, which are not in the author's area of responsibility, a liability claim only becomes effective if the author knows the contents and if it was technically possible and reasonable to him to prevent the utilization in case of illegal contents. Thus the author explicitly declares that to the moment he put the link the corresponding web sites were free of illegal contents. The author has no influence whatsoever on the current and future design and on the contents of these linked pages. Therefore he dissociates explicitly from all contents of the linked pages which were modified after he had put the link. This declaration is valid for all links and cross references within his own internet offer and also for external entries in guestbooks, discussion fora and mailing lists set up by the author. For any illegal, incorrect or incomplete content and especially for claims which occur because of the utilization or non-utilization of such information, it is not the author who assumes the responsibility, because he only refers to the particular publication, but the provider of the particular web site to which the link was put. 

3. Copy right and labelling right 

The author is anxious to respect the copy rights of the used pictures, audio and video documents and texts in all his publications, to use pictures, audio and video documents and texts prepared by himself or to resort to public domain pictures, audio and video documents and texts. All trademarks mentioned in the online offer and, as the case may be, protected by a third party, underlie the terms of the corresponding valid labelling rights and the rights of property of the corresponding registered owner without restrictions. Only by mentioning trade marks the conclusion cannot be drawn that these trademarks are not protected by the rights of a third party. The copy right for objects published and prepared by the author himself remains with the author of the pages. A duplication or utilization of such pictures, audio and video documents and texts in other electronic or printed publications is not allowed without the author's explicit approbation. 

4. Legal effect of this disclaimer 

This disclaimer is to be seen as part of the online offer, from which was referred to this page. Should parts or single formulations of this text not, no longer or not completely correspond to the valid legal position, all other parts of the document rest thereof unaffected in their contents and validity.
