The wireless network is accessible to all users of the library and covers the entire library. To gain access to the network, you need to log on to 'eduroam' or 'KB-Guest' - the latter requires that you accept the conditions for use. 

Internet connectivity requires that you are from an institution that is part of the Eduroam collaboration. Contact your own institution to get information on how to access Eduroam.

Lockers are found on the ground floor and on the 1st and 4th floors. The lockers are operated via a four digit pin code of your own choice. If your bag or suitcase is too big for the lockers, we have extra large ones. Talk to the staff at The Black Diamond Information services and they will help you.

You will find the cloakroom to the left of the main entrance, right by the toilets.

Students can reserve and borrow a locker. Students writing their thesis can borrow the locker for up to six months. Other students can borrow the lockers for two months at a time. Contact The Black Diamond Information services to hear more.

We have prioritised making room for you and your laptop in our study areas, but there is a small number of computers available for general use in the public areas on the 2nd floor. The computers require a password and may be used according to a first-come, first-served policy.

Toilets are found on the ground floor on each side of the atrium. In addition, there is a small toilet located on the second floor (same floor as the three large reading rooms).

In The Black Diamond shop, you can get answers to your questions, become acquainted with the library services, pick up and return borrowed material, purchase unique products, and get help finding exciting cultural experiences. You can find us just inside the revolving doors by the main entrance.

Besides common office supplies and books, the shop also offers unique products with quotes and motifs from the collections, such as tote bags, notebooks, and fridge magnets.

It is also possible to buy select products, books and posters in our webshop.
