The Cooperative Library Network Berlin-Brandenburg (KOBV) is the association of all university and university of applied sciences libraries, all public libraries and numerous special and public libraries in the Berlin-Brandenburg region. Responsible for the KOBV are the states of Berlin (Senate Department for Culture) and Brandenburg (Ministry of Science, Research and Culture) as well as the participating libraries. The KOBV was founded in the years 1997-2000 and institutionalized in 2001. The aim of the KOBV is to improve the regional information infrastructure and to develop new services for users. The KOBV feels particularly committed to the Open Access movement and Open Science. The central coordination unit of the network is the KOBV headquarters at the Zuse Institute Berlin. In addition to service and consulting tasks, the KOBV headquarters also takes on development tasks in the form of projects. The KOBV cooperates closely with the Friedrich-Althoff-Konsortium e.V. (FAK) and the Research and Competence Center Digitalization Berlin (digiS), which are also located at ZIB.
