Our literature search engine stabikat+ is a discovery system which allows users to search in several hundred million journal articles, books, references from bibliographic databases and other resources. In many cases it is possible to directly access full texts. Stabikat+ currently includes the records of the StaBiKat and provides access to the databases subscribed to by the Staatsbibliothek and to electronic journals as well as full texts from Open Access repositories and other resources.

The online catalogue of the Staatsbibliothek zu Berlin - StaBiKat - contains books and journals holdings as well as electronic media. Readers can search by author, title, etc. and also carry out subject searches. Article titles have not been included. A part of the holdings of the special collections departments of the Staatsbibliothek can be found in specialist online catalogues.

Traditional subject catalogues complement the online version the old classified catalogue - Alter Realkatalog (ARK) which is currently under development.

A part of the holdings of the special collections departments of the Staatsbibliothek are still only recorded in traditional catalogues. The departments provide information on their respective catalogues.
