The online catalogue StabiKat  is a discovery system and is currently available in a beta version. It allows users to search over 60 millions of journal articles, books, journals, databases and more available in print or online at the State Library. 

The classic online catalogue StaBiKat classic will continue to be available until further notice. It can be reached via StabiKat  or directly. Readers can search by author, title, etc. and also carry out subject searches. Article titles have not been included.

The reading room classification (only in german) assists you in thematic searches for volumes in the reference holdings of the general reading rooms of both houses, the rare books room and the Eastern European room. Important electronic resources are also assigned to these classification points.

Subject Search 1501 - 1955 is the online version of the historical classification covering around 3 million volumes of the old holdings of the Staatsbibliothek. The basis is a library catalogue of many volumes – the Old Subject Catalogue (Alter Realkatalog - ARK). It is possible to browse the systematic classification or to search with different search terms over more than 225,000 subject access points. There are direct links to bibliographic records in the online catalogue StaBiKat.

A part of the holdings of the special collections departments of the Staatsbibliothek can be found in specialist online catalogues.

A part of the library‘s special collection holdings is exclusively recorded in traditional print or card catalogues. The special departments provide information on their respective catalogues.
