Most libraries in Denmark public as well as Educational and research libraries (aka FFU) are publicly funded. Though they are independent organizations, they are tied together by a cooperative network of functionality and dependencies.
Danish citizens have a free right to borrow materials from ANY public library in Denmark - free of charge. This service does to some extent includes the educational and research libraries.
As well as a free right of loans for the borrowers, libraries are by law obliged to support interlibrary loans - also free of charge for the borrowers.
Since the mid 1970’s libraries in Denmark have exchanged cataloguing records via a union catalogue called Danbib.
The Danbib catalogue and the holdings from libraries participating in the inter library loans cooperative are combined in the Bibliotek.dk system. This is a portal to the common public functionality of the danish libraries (search catalogue, reservation and holdings). Another part of Bibliotek.dk is a service to exchange reservations and Inter Library Loans. This service is highly automated and has a set of rules for reservations and delivery. Public libraries exchange reservations (and materials) via central libraries (Centralbiblioteker) - a regional service. All libraries are serviced by a national transport service for library materials (Kørselsordningen) which makes exchange of items between individual libraries nation wide possible on a nearly day to day basis. The individual libraries themselves handles items between the branches.
Public libraries are funded and organised by the individual municipalities in Denmark and normally have a main library in a major town with smaller branch libraries in other towns and a mobile library service covering rural areas. The basic library services (loan, reservations) are free of charge for users with residence in Denmark (including expatriates).
