Disclaimer
With regard to any direct or indirect references to external websites ("hyperlinks") that are beyond the sphere of responsibility of the author, any liability obligation would only come into effect in the event that the author is aware of its content and it is both technically feasible for the author and reasonable to expect the author to prevent use if such external websites contain illegal content. The author hereby expressly declares that, at the time when the link was created, no illegal content could be detected on the sites being linked to. The author has no influence over the current and future design, content or copyright situation of the linked sites. As a result, the author expressly disassociates himself from all contents on all linked sites which have undergone changes after the link was set. This statement applies to all links and references that are set within the author's own website as well as to entries made by external persons in guest books, discussion forums, link directories and mailing lists set up by the author, and to all other forms of database which may be accessed externally for the purposes of information input. Solely the provider of the site to which the reference is set shall be liable for illegal, incorrect or incomplete content and in particular for damage or losses attributable to the use or non-use of information offered in this way; the person who merely refers to the publication in question by means of links shall not be liable.

Copyright and right of identification 
In all publications, the author shall make efforts to comply with the copyrights to the pictures, graphics, audio files, video sequences and texts that are used; the author shall attempt to use pictures, graphics, audio files, video sequences and texts that he himself has created, or else to employ graphics, audio files, video sequences and texts that are not subject to licenses. All brand names and trademarks stated within the website which may be registered by third parties are subject without limitation to the provisions of the particular identification law which applies and to the property rights of their particular registered owners. Simply stating such names does not provide grounds for concluding that the brand names are not protected by the rights of third parties! The copyright to published items created by the author himself is retained exclusively by the author of the web pages. Duplication or use of such graphics, audio files, video sequences and texts in other electronic or printed publications without the express authorization of the author is not permitted.
