14.04. – 16.04.25: OPUS is only available for research

Please note:

From Monday, 14th April to Wednesday, 16th April 2025, OPUS will only be available for research.
No publications, examination papers etc. can be uploaded or edited during this period.
The reason for this is the changeover to a new version of the software.

We ask for your understanding.

Please note that the submission of printed dissertations and documents is only possible by prior arrangement (tpu@ub.uni-siegen.de).

You can publish your documents quickly and easily on OPUS Siegen. Professional content indexing through metadata makes your document searchable via local, national and international search services. Thus, it is quickly available worldwide, independent of time and place.

The permanent archiving of your documents is guaranteed in OPUS Siegen. All documents receive a DOI (Digital Object Identifier) and a Uniform Resource Name (URN), which are stored together with the document on the OPUS server and the archive server of the German National Library and guarantee a permanent and stable addressing.
