Edit. 22th September 2023: Problem solved.
Due to an error situation that occurred during the hardware update, the cash register in Töölö Campus Library is out of order and paying any library charges is currently impossible there. The error is being investigated and will corrected as soon as possible.
In the mean time library charges can be paid at the customer service in Sörnäinen Campus Library. You can also pay unpaid late fees online: instructions for online payment.
We apologize for the situation.
