The Primus search portal is the central search interface of the University Library of the Humboldt-Universiät for the subject searches in its holdings. Equipped with modern search technology, you can quickly and effectively search in Primus and directly access full texts or get to the books. The search includes the classic printed holdings of a traditional online catalogue, but also our extensive e-book packages and many articles from electronic journals. The search area "HU Catalogue, articles and more" is based on the Central Discovery Index. Please also see our video tutorials (in German only) and search tips on Primus.
In the German Union Catalogue of Serials (ZDB) you can search for magazines and newspapers throughout Germany and find out which volumes are available in the libraries. Regarding Berlin and Brandenburg libraries, please note the regional abbreviation BER.
The Digital Collections give you access to already digitized collections of the HU University Library.
Special Research Portals offer a wide range of search options and provide an overview of the literature available in a particular subject area in Germany.
