The issue concerning the institutional repositories is intimately related to the concept of free access to research results to increase

visibility, impact and sharing of scientific information. Academic and research institutions worldwide increasingly adhere to the open access paradigm through the establishment of institutional repositories aimed to fully maximize the visibility of their research outputs. The two main tools collecting timely data on the number of such digital archives are the Registry of Open Access Repositories (ROAR) [18] and Open DOAR, Directory of Open Access Repositories [19] respectively count 2049 and 1815 installations all over the world. Visibility find more and impact of repositories are also constantly monitored by using web indicators as shown twice a year (January and June editions) Stem Cells inhibitor on the Ranking Web of World’s Repositories [20]. The building-up and maintaining of the institutional repositories foster close interaction between diverse categories of professionals: the information specialists dealing with the quality control and standardization of bibliographic data, the data management experts designing the workflow of data handled by the users, the institutions’ managers (administrators) defining official policies and

the researchers providing their papers to be posted to the repositories (self-archiving procedure). Digital repositories complying with the standards set by the Open Archives Initiative (OAI) [21], are called “”interoperable”"; interoperability is the capability of exchanging data aiming to facilitate the efficient dissemination of Ralimetinib cost content. This means that users can find their contents without knowing which archives exist, where they are located, or what they contain. OAI-compliant archives are based, built and maintained on open-source software. Such digital containers give great visibility to scholarly literature

on the web; this is proved by the fact that the traditional search engines, as Google, present them as first Etomidate results of the queries launched by the users. Institutional repositories, as digital containers of research output, have definitely to be conceived as strategic tools to manage, spread and preserve research information within an institution. They essentially work as stable windows online to timely show up the resources produced by the scientific community. In this respect, the awareness of researchers as authors and readers of scientific literature is fundamental, as each individual publication is by now, in the Internet era, part of a global information network.
