Privacy Policy

Every time the internet presence of the Narcotic City Archive is accessed by a user and every time a file is downloaded, for technical reasons data relating to this procedure are temporarily saved and processed in a protocol file.

Specifically, at every access/download, the following data are saved:
•     the IP address, which is (subsequently) anonymised,
•     date and time,
•     page accessed / name of file downloaded,
•     quantity of data transferred,
•     a message on whether the access/download was successful.

These data are evaluated only for statistical purposes and to improve the quality of service and are then destroyed. No other use is made of them and they are not passed to third-parties.

When accessing specific pages, so-called ‘session cookies’ are used to facilitate navigation. These session cookies hold no person-specific data and expire when the session is over. Technologies that enable tracking of the user’s browsing habits, such as Java Applets or Active-X Controls, are not used.
Postal and Email addresses stated in the context of queries or requests for information are used solely for the purpose of correspondence and postal delivery, respectively.

We are committed to protecting your privacy. To the archive and the KWI, the protection not only of your personal but the safety and security of all data that flows through our institution is important.

As part of this effort, we process personal data in accordance with the German Data Protection Law and, where applicable, with EU’s General Data Protection Regulation (“GDPR”). This Privacy Policy may change from time to time.

Universität Duisburg-Essen K.d.ö.R. is responsible in questions of complying with data protection laws, especially the EU General Data Protection Regulation (GDPR).

Where known, the NCA provides information about copyright owners and terms governing the appropriate use of materials. This information can be found in the description of an item in the catalogue. Due to the nature of historical collections, however, we are not always able to identify copyright holders or to provide correct information.

It is the patron's obligation to determine and satisfy copyright or other use restrictions when publishing or otherwise distributing materials found in the NCA’s collections.
The NCA does not intermediate in questions about copyrights held by third parties.
Unless NCA holds copyright to an item, we cannot give or deny permission to publish or to otherwise distribute it. Permission and possible fees may be required from the copyright owner independently of the NCA.
