It also operates a public library with an extensive literature stock and large collection of other references in the field of spatial planning.
The UIRS performs basic and applicative research projects at the international, national, regional and local levels, addressing various issues and processes of the urban and spatial development of Slovenia and the wider area. Research activity also includes the advancement of methodological and practical solutions for the development of urban areas, and planning of settlements and the countryside.
