Content of the Online Offer

The author assumes no liability for the topicality, correctness, completeness or quality of the information provided. Liability claims against the author relating to material or immaterial damage caused by the use or non-use of the information provided or by the use of incorrect or incomplete information are excluded, unless there is evidence of willful intent or gross negligence on the part of the author.

All offers are subject to change and non-binding. The author expressly reserves the right to change, supplement or delete parts of the pages or the entire offer without prior notice or to discontinue publication temporarily or permanently.

References 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 technically be able to prevent the visitors of his site from viewing those pages.

The author hereby expressly declares that at the time the links were created, no illegal content was recognizable on the linked pages. The author has no influence whatsoever on the current and future design, content or authorship of the linked pages. The author therefore expressly distances himself from all contents of all linked pages that have been changed since the link was created. This statement applies to all links and references set within the author's own Internet offer as well as to third-party entries in guest books, discussion forums and mailing lists set up by the author. For illegal, incorrect or incomplete contents and in particular for damages arising from the use or non-use of such information, the provider of the page to which reference is made is solely liable, not the party who merely refers to the respective publication via links.

Copyright and Trademark Law

The author endeavours to observe the copyrights of the graphics, sound documents, video sequences and texts used in all publications, to use graphics, sound documents, video sequences and texts created by himself or to make use of licence-free graphics, sound documents, video sequences and texts.

All brands and trademarks mentioned within the Internet offer and possibly protected by third parties are subject without restriction to the provisions of the applicable trademark law and the ownership rights of the respective registered owners. The mere fact that a trademark is mentioned should not lead to the conclusion that it is not protected by the rights of third parties!

The copyright for published objects created by the author himself remains solely with the author of the pages. Any duplication or use of objects such as diagrams, sounds or texts in other electronic or printed publications is not permitted without the author's agreement.

Data Protection

As part of its participation in the German Library Statistics, the Herzog August Bibliothek uses a procedure for counting visits to its website. When calling up the homepage and/or the catalogue page ("OPAC"), an identifier of the library and the page concerned, the time of the call and a signature of the calling computer are stored. The signature is generated using a one-way function consisting of IP address, browser identification and proxy information. The collection, storage and evaluation of this data takes place in pseudoanonymised form, i.e. the signature cannot be assigned to specific persons. The IP address in particular is not stored. The pseudonymous individual data are summed up after 24 hours at the latest and thus anonymised.

The stored data is statistically evaluated in order to design and further develop our website in line with requirements. The data will only be used for this purpose and will be deleted after evaluation.

The Stuttgart Media University is responsible for the technical and organisational implementation of the procedure. It has developed the procedure in accordance with the provisions of the Data Protection Act and the Telemedia Act (TMG) and undertakes to comply with them.

You have the opportunity to object to the collection, processing and use of the aforementioned data of your visits for the aforementioned purpose. Please click on the following external [Link].

If the opportunity for the input of personal or business data (email addresses, name, addresses) is given, the input of these data takes place voluntarily. The use and payment of all offered services are permitted – if and so far technically possible and reasonable – without specification of any personal data or under specification of anonymized data or an alias.
