With a view to approximately 100,000 media, the German Police University maintains one of the largest and high performing police libraries in Europe. It is not only accessible to German Police University staff members, but also to external students and scientific staff, the latter, however, only after prior phone registration and as a reference library, i.e. without the possibility of borrowing items. Internet access is just as self-evident as access to legal information and search systems and other research facilities for police literature.
