The State and University Library Bremen (SuUB) is the city's largest and oldest academic library. As the designated central library of the Free Hanseatic City of Bremen, the SuUB supplies literature to universities and colleges across Bremen and Bremerhaven, while also acting as the state and depository library.
Centrally located on the university campus, the SuUB is the main provider of library services to the University of Bremen. The SuUB's integrated library system is comprised of a central library and a number of decentralized departmental and branch libraries located in close proximity to individual departments and higher educational institutions in Bremen and Bremerhaven. The library’s entire holdings are cataloged and indexed in a common circulation system, which operates across all nine sites.
