In 2008 the Ljubljana City Library as a legal successor to the Oton Župančič Library became the central regional library (CRL) of the central Slovenian region. The Librarianship Act states that CRL is a library, which on the grounds of a contract with the Ministry of Culture and by consent of its founder handles certain special tasks for a wider region.
The Central Slovenian region covers 16 % of the Slovenian territory (29 municipalities) and 25 % of the whole population of Slovenia (550 000 inhabitants). Beside the municipalities of the Ljubljana urban region it also covers three municipalities of the Inner Carniola: Cerknica, Bloke and the Loška dolina.
The LCL’s network unites 35 libraries, of which beside the Slovanska Library and the Trubar Literature House, 21 are located in Ljubljana, while 14 are operating in the suburban municipalities: Brezovica, Dobrova – Polhov Gradec, Horjul, Ig, Škofljica, Velike Lašče, Vodice, Medvode ter Dol pri Ljubljani.
