The BIS offers a broad spectrum of academic information and services at both locations.
When the Carl von Ossietzky University was founded in 1973, the BIS took over the holdings of the former Pädagogische Hochschule. Today the University Library has around 1.4 million books in its open-stack shelves.
The collections focus on the academic disciplines represented at the University.
The Central Library on Haarentor Campus houses specialised literature on the humanities, cultural studies, economics, social sciences and law while the Departmental Library on Wechloy Campus has literature for the natural sciences, engineering, mathematics and medicine.
The BIS provides access to a constantly growing selection of electronic resources such as e-books and academic databases and also has approx. 25,000 electronic journals.
The subject-specific information pages provide access to specialised databases, electronic journals and other research instruments as well as additional information on courses and support services in your subject area.
The University Library's catalogue lists the BIS's entire print and electronic media holdings.
The BIS also has a large number of rare collections and archives.
