Urbani izziv/Urban Challenge 1989–2009 (Part 1)
Urbani izziv/Urban Challenge is a periodical publication from the Urban Planning Institute of the Republic of Slovenia, which has been published for the last 20 years. The first issue was published in December 1989, upon the 30th anniversary of the Urban Planning Institute. During these years, the journal has developed into the leading scientific-professional publication in Slovenia in the dissemination of scientific and professional knowledge and a forum for open discussions about the problems relating to spatial planning and management in Slovenia and abroad. Until 2008, (volume 19) each issue had a leading theme. From 2009 (starting with volume 20) issues are no longer thematically oriented. By this means, the journal has been “opened”. In each issue contributions regarding different “spatial” themes can be published, and from various scientific fields and disciplines (e.g., architecture, land­scape architecture, geography, sociology, economics, etc.), presenting the scientific and expert interests of authors within the fields of study, such as spatial planning, urban planning and design, landscape planning and design, regional development, natural and cultural heritage protection, environmental protection, spatial informat­ics, housing and traffic studies, access for the disabled, etc.
On this occasion, the journal Urbani izziv/Urban Challenge ceased publishing the­matically oriented issues, the list of all thematic editions were prepared. In this issue the list of editions of the first decade are also published, while the list of issues of the second decade will be published within the next edition. Most issues are still in stock and available at a very favourable (symbolic) price.
