The majority of NUK collections are kept in closed stacks. Information about library materials is held in NUK Catalogue. Members of NUK can log in to search and reserve items in advance through NUK Catalogue.
Please note:

• only members of NUK are eligible to borrow materials 
• materials can be used in the Main Reading Room, Periodicals Reading Room, or in reading rooms of special collections or can be borrowed outside the library on loan 
• materials that cannot be removed from the library can be copied.

Requests for library materials from other Slovenian or foreign libraries are limited to materials which NUK does not own and can be ordered through interlibrary loan service. All services are charged according to the valid price-list.
