Two-thirds of the library’s holdings are available to anyone for ordering via the online catalog or with a lending slip (Ausleihzettel) from the stacks [online catalog shows location: “Magazin”] and can then be checked out to the reading room or for home use. Orders can be placed via the online catalog or from the Primo library portal. To order a book from the stacks or reserve an item that has been checked out, you need to sign in to the online catalog or Primo using the user code shown in your student or user ID.
