The archive at Bielefeld University fulfils its remit as a public archive on the basis of the archive legislation of North Rhine-Westfalia from 16 March 2010 (ArchivG NRW), the archive legislation and regulations on fees of North Rhine Westfalia from 15 June 2010 (ArchivNGO NRW) as well as the University's own Regulations on the storage, selection, archiving, and destruction of files from 9 December 2003. It abides by these regulations by collecting documents and publications which are produced by the bodies and institutes of Bielefeld University and show historical value. Accordingly, the archive keeps these safe, supplements, preserves, maintains, indexes and makes them available for use and carries out and publishes research itself. In addition, the archive supplements its official collections through the acquisition of bequests and papers of associations from Bielefeld and its surroundings as well as the through the creation of archival collections in relation to the University (photos, placards, leaflets, sound and film documents etc.).
At the same time, the University Archive is a service that prepares and makes available information for various groups of users within and external to the University (students, scientists, staff, people interested in history etc). In addition, the Archive advises the University on questions of file management, maintaining files or disposal. Finally, the Archive should take an active role in shaping tradition and promoting an identity with the aim of anchoring the University through its history in the public awareness of the region.
