The paper explores the potential role of Institutional Repositories for processes of evaluation of research results. It presents a methodology for the definition and classification of the content of Institutional Repositories that will be useful to outline the standards of comprehensive, comparable and defined outputs, to select those corresponding to the different mission and institutional activities carried out by research organizations (Universities and Public Research Institutions). The research question is: what is the value of the Institutional Repositories for the evaluation of public research organizations even beyond research activities? What kinds of output should an Institutional Repository contain to respond to both scientific requirements and comparability assumptions in the evaluation process, besides the sharing capacity and the flexibility inherent to the notion of Open Science? Through a case study on a specific Institutional Repository (CNR National Council), the paper proposes a conceptual framework to address the research questions, which is supposed to contribute outreach purposes, evaluation and sharing of science.
