OPUS - FAQs - General Information

What is OPUS?

OPUS is a publication platform for electronic documents at universities, founded in Stuttgart in 1998. OPUS is now used at numerous German universities. OPUS records and archives electronic full texts relevant to research and teaching. This means no documents with current or quickly outdated content, such as conference or lecture announcements, references to courses, etc., are included. Rather, the results and content of such events are included in OPUS in an unabridged form. OPUS offers all members of Trier University the opportunity to publish academically relevant documents in electronic form.

The German Copyright Act (UrhG9) applies without restriction to documents offered in electronic form via data networks.

The following applies in particular:

Individual reproductions, e.g., copies and printouts, may only be made for private and other personal use (Section 53 Copyright Act). The production and distribution of further reproductions are only permitted with the author’s express authorization.

In any case, you should clarify the copyright and license aspects before electronic publication to ensure that the publication does not conflict with any third-party rights.

If you also want to publish the work with a publisher, you can do so without further ado. However, the publisher must agree to the University Library’s electronic publication.
