The Göttingen State and University Library (German: Niedersächsische Staats- und Universitätsbibliothek Göttingen, or SUB Göttingen; English short form: Goettingen SUB) is the library for Göttingen University as well as the central library for the German State of Lower Saxony (with its central catalogue), and the library for the Göttingen Academy of Sciences. It also houses the Göttinger Digitalisierungszentrum (Center for Retrospective Digitization), the GBV regional library consortium offices, and numerous projects in librarianship and related fields as well as providing such online services as its virtual library and vascoda.
One of the largest libraries in Germany, the Goettingen SUB houses some 4½ million volumes as well as 13,000 holographs and other manuscripts and 350 Nachlässe (literary remains). The library works under a dispersed system, with numerous branch libraries located in various academic departments, supplementing the central collection housed in the new library building (construction completed in 1992) on the main campus and the historical library building in downtown. The library is responsible for a number of special-area collections (Sondersammelgebiete) under the German national library system. The historical library building holds manuscripts, rare books, and a significant history-of-science collection and research facility as well as works in the special-area collections, old-stock and other items. In addition, its original core, the Pauliner Church, has been made through adaptive re-use and reconstruction into an exhibition and lecture center. All newly accessioned materials as well as almost all old holdings are electronically cataloged; a small number of old holdings (some of those from the 1940s–1970s) are only searchable electronically using a "virtual catalogue." The library holds a large collection of academic database CD-ROMs, an extensive collection of micro-forms, and collections of aural and audio-visual media.
In cooperation with the University Library "Georgius Agricola" of the Technische Universität Bergakademie Freiberg (UBF), the SUB maintains a large online collection of geoscience-related materials, the GEO-Library Experts Online, or GEO-LEO.
In the year 2002, the Göttingen SUB won the German Library of the Year (Bibliothek des Jahres) award.
The library possesses a Gutenberg Bible (one of only four perfect vellum copies known to exist).
