Online catalog/lending

Search and order in KatalogPlus

The KatalogPlus (discovery system) replaces the OPAC (online catalog).

All of the library's resources - its own and licensed - can be searched centrally via a comprehensive search engine index. Books, articles, sheet music, sound recordings, printed and electronic, including full texts available online, can be searched in one place.

In many cases, the document in the respective resource can be accessed directly from the results list.

KatalogPlus offers a standardized hit list, fast response times, relevance ranking and faceted search results. Faceted browsing allows the search to be narrowed down step by step.

The KatalogPlus is constantly being improved and adapted. If you have any suggestions or change requests, please let us know at
