Since 1992, the open access holdings (with the exception of journals and final theses) of the university library have been indexed according to the decimal classification (DK).
An overview of the available DK classes can be found directly below: UDC
When searching for terms in the "Free search" input field, all indexed data entered to describe a medium in the catalogue are taken into account. Since the title or subtitle of scientific literature precisely describes the content of a medium, relevant hits are to be expected when searching with a keyword.
All available titles can be searched via the OPAC library catalogue.

Via the Database Information System (DBIS) you can find subject databases licensed by the library or freely accessible on the Internet.
