Lending and use on library premises

Information on the use of books, journals and newspapers as well as further information on loan periods, extensions of loans, reservations, return of media items or their loss. In addition, we will answer frequently asked questions on loans and use on the library premises.


lending deskThe path to printed media leads to the search portal bonnus, where you will find the call number and location of the required book or journal. This information will be given under "Holdings Uni Bonn". Depending on the location of the media item, it is directly accessible for you or can be ordered via bonnus. However, not every media item can be borrowed for home use. Some items can only be used on the library premises.
Electronic media can also be found in bonnus. They cannot be checked out, but can be accessed within the university network at all times.


  • 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.
  • Reading room or Curtius Reading Room: The book can be consulted on the premises, but cannot be checked out for home use.
  • Closed stacks: The book has to be requested via bonnus. You will be given 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. A link to the opening hours and the address of the respective institute can be found under "Holdings Uni Bonn". As a general rule, the institute's books cannot be checked out, but can be consulted on the library premises. 


Journals cannot be checked out for home use and can only be consulted in the library.

Bonn University’s employees can borrow books for a longer period of time, but only until someone places a hold on the book. If you need such a book, please place a hold on it. The employee will then be asked to return the book.

For displaying the order function, the hold as well as for information about the expected date due for return of borrowed items, it is necessary to select the branch library where the media item is situated. The default setting is the branch library “Main Library”. If you would like to, for example, order a book from the departmental library, please select “MNL” in the top right corner beforehand.
