The media stock comprises approx. 45,000 items, which are listed campus-wide in the Alephino catalog system. An extensive online offering of e-journals, e-books, subject and literature databases is available to users around the clock. Furthermore, the library collects the publications of Hereon staff in a database and advises on open access publishing.
