Knowledge is networked. All our offerings contribute to a globally distributed system of scientific information - comparable to a global ecosystem. Knowledge in all its forms has to be reliably processed, refined, stored and made available for dissemination. The knowledge infrastructure at the Göttingen site is based on diverse processes for printed and other material media and for digital information resources as well as tools. For example, as the central hub for the national book transport service, the Göttingen State and University Library traditionally secures part of the literature supply for all of Germany. Hundreds of websites and databases as well as partly highly specialized tools are operated by the Göttingen State and University Library to help students and researchers in Göttingen or to be part of the knowledge infrastructures in Lower Saxony, Germany, Europe or worldwide. This is based both on modern digital infrastructures and analog control technologies as well as on the specialist personnel required for this purpose in areas ranging from software development to inhouse and logistic services.
