Since last week, the ventilation system in the Main Library has been experiencing repeated malfunctions, each of which has to be rectified manually.
The relevant departments have been informed and are working to keep the air quality and temperature as stable as possible. However, fluctuations may occur; these are being monitored continuously.
In isolated cases, we may be forced to temporarily close parts of the public area in the Main Library at short notice.
We thank you for your understanding.
