Our offer contains links to external websites of third parties. On whose contents the author has no influence. Therefore, the author can not assume any liability for these external contents. The respective provider or operator of the pages is always responsible for the contents of the linked pages. The linked pages were checked for possible legal violations at the time of linking. Illegal content was not recognizable at the time of linking. However, a permanent content control of the linked pages is not reasonable without concrete evidence of an infringement. Upon notification of rights violations, such links will be removed promptly. Therefore, the author hereby expressly dissociates himself from all contents of all linked pages that were changed after the link was set. This statement applies to all links and references within the own internet offer. For illegal, incorrect or incomplete contents and in particular for damages resulting from the use or disuse of such information, the provider of the page to which reference was made, not the one who only links to the respective publication.
