Hot Days. Cool Books.

18/06/2026

Thanks to the central cooling system and shaded windows, the library is a great place to read and study during the summer months.

Drinking Fountains & Bottle Filling Station

To quench your thirst, drinking fountains are available in the Central Library as well as in the Library for Law. You can also bring your own water bottle and refill it on level 4 in the Central Library.

Summer Opening Hours

From June 29 to September 25, the Central Library will be open from 8:00am to 8:00pm. From June 29 to August 28, the Library for Law will be open from 9:00am to 4:00pm.

Summer Closing Times

We are using the summer weeks to carry out necessary cleaning and maintenance work. The Central Library will therefore be closed from July 15 to August 2. The Library for Law will be closed from August 10 to August 14.
