    For Corona prevention, the following regulations currently apply (more information here):

    1. FFP2 mask and hand disinfection: Wearing an FFP2 mask and disinfecting your hands beforehand, e.g. at the disinfection stand provided for this purpose, are compulsory.
    2. Scan QR Code: When entering the library, please scan the QR code at the entrance with your smartphone. Then directly indicate your planned attendance (30 min, 60 min etc.) when entering. If you do not know how long you will be staying, you can instead select "Check-In" when entering and then scan the QR code again when leaving and select "Check-Out". (If you do not have a smartphone, you can print out a personal QR code in advance; see chapter 3.3 in the Secure Contact Tracing at HNU guide).
    3. Book basket: Take one library basket per person, even if you would not normally need a basket. (We can use the counted baskets to ensure that the permitted number of people is not exceeded). When leaving the library, place the basket on the separate basket return pile.
    4. Distance: Keep a distance of 1.5 metres from other people, even during any waiting time.

    If you have any questions, please feel free to send them by e-mail to During our opening hours, you can also reach us by phone at 0731/9762-2706.
