How can I borrow a book?

  • Textbook collection or open stacks: make a note of the call number, take the book out of the shelf yourself and take it to the issue desk. Required books can be researched via the search portal bonnus.
  • Reading room or Curtius Reading Room: The book can be consulted on the premises, but cannot be checked out for home use. Please note our information on use during the Corona pandemic.
  • Closed stacks: The book has to be requested via bonnus. The system will give you a date when you can pick the book up.
  • Departmental libraries: bonnus does not only display the collections of ULB alone, but also the departmental libraries' collections.

How can I use e-media items from home?

Dialling into the university network is always done via the personal account (Uni-ID and password) that students receive at the time of registration and members of staff at the university computer centre.

It is necessary to use a so-called VPN-Client for dialling in. This free of charge additional software allows a secure connection between any PC with internet access and the data network of the university.
