In the frame of Tempus project „New library services at Western Balkan Universities“ (2010–2013) digital repositories on universities in three Western Balkan countries were established. Since the institutional repositories of the universities were designed for archiving digital objects in all fields of science, the need for single classification scheme has emerged.

Classification system OSNO (General Scheme of Scientific Fields) has been developed by the team of librarians at the University library Svetozar Markovic in Belgrade and incorporated in the institutional repository of the University of Belgrade PHAIDRA BG, as well as in institutional repositories of the Universities of Kragujevac and Nis. It has also been used by Universities in neighboring countries: Montenegro (University in Podgorica) and Bosnia and Herzegovina (Universities in Sarajevo and Tuzla). The scheme is addition to the initial application based on PHAIDRA system developed at the University of Vienna.

Classification scheme OSNO is mandatory for scientific objects because it enables comprehensive information retrieval. A general scheme of sciences and scientific areas presented in natural language has been developed in order to make entry of content descriptions of scientific documents easier for users. At the moment librarians are uploading documents, mostly doctoral theses into institutional repositories. OSNO is user-oriented scheme, designed upon the notion that it will be used not only by librarians, but by researchers as well.

This paper presents classification scheme OSNO and information retrieval system which uses specific scientific areas from a drop-down menu as the search criteria.
