Where our site contains hyperlinks that lead directly or indirectly to other websites for which the University Library Frankfurt bears no responsibility, the University Library Frankfurt is only subject to liability claims where the Library has full awareness of the content in question and where it would be both reasonable and technically possible for the University Library Frankfurt to prevent illegal usage of the content in question. The University Library Frankfurt hereby explicitly states that at the time the link was placed, there was no evidence of illegal usage of content on the site(s) to which the link led. The University Library Frankfurt bears no responsibility for the current and future content, structure or any possible copyrights on the sites in question. For this reason, the University Library Frankfurt hereby explicitly refuses to claim responsibility for the content of all sites linked to ours where the content has been modified after the link was placed. This applies to all links both direct and indirect placed on our own website and to contributions made by external parties to guest books, discussion forums and mailing lists set up by the University Library Frankfurt. In the case of illegal, defective or incomplete content and especially regarding any damages resulting from the use or non-use of information of this kind, liability is borne solely by the party operating the website to which our website provides a link, and not the party which has simply referred users to the publication in question via a link.
