Digital Repository

To register your publications (e.g. articles in academic journals) in the University Bibliography please fill in the form in UBICO.

OPUS is a service that allows staff members and students of Brandenburg University of Technology Cottbus-Senftenberg to publish scholarly documents (journal articles, doctoral theses, conference proceedings etc.) free of charge on the Internet. The documents will be freely available, archived permanently on the OPUS server and easy to find by search engines.

The Digital Repository OPUS offers a button (top left) to switch to the English surface if necessary.

DOI service

You will receive a free DOI (Digital Object Identifier) for your online publication. The unique identifiers enable the permanent availability of electronic doucments and simplify their referencing. Your DOI will be generated before your document is published and the link should be included in your file.

Use the registration form to upload all needed metadata to the Digital Repository (OPUS). We will then generate the DOI for your publication and and inform you per e-mail. Please include the DOI in the imprint of your document. For doctoral theses, the designated place is the lower left corner on the back of the title page.

One electronic document cannot be assigned more than one DOI. A subsequent DOI generation for documents already published via OPUS is not possible. The DOI-Service of the University Library of the BTU Cottbus-Senftenberg is operated in cooperation with the TIB Hannover / DataCite.
