The open access repositories activities in Portugal are undergoing a strong momentum as the reflex of the growing interest and involvement of the Portuguese academic and scientific community in the questions related with Open Access to scientific literature.
 
In Portugal, the development of Open Access has mostly been carried out by the universities, who have taken different initiatives to expand access to research information. The first Portuguese Open Access initiatives were initiated by the University of Minho with the creation of RepositóriUM - its institutional repository (October 2003) and the subsequent definition of a pioneering self-archiving policy (January 2005). In early 2008, CRUP resent to the Portuguese Ministry of Science, Technology and Higher Education (MCTES) by resending the Conference of Rectors of the Portuguese Universities Declaration on Open Access and stated its support for the recommendations from the European University Association (EUA) Working Group on Open Access. In the middle of 2008, the RCAAP (Repositório Científico de Acesso Aberto de Portugal = Portugal Open Access Science Repository) initiative was established. The RCAAP initiative aims to increase the visibility, accessibility and dissemination of Portuguese research outputs, as well integrating Portugal worldwide in this domain. RCAAP Portal: collects, aggregates and indexes open access scientific contents from Portuguese institutional repositories, and forms a single entry point for searching, discovery and viewing thousands of scientific and scholarly publications.The main components of the RCAAP project are the following:
Currently, there are in Portugal 51 scientific open access repositories in a production stage and aggregated in the national portal - RCAAP Portal. Altogether, the running IR’s, gather more than 600 000 scientific documents in open access. The repositories which seem to have higher degrees of success are those with self-archiving policies implemented.
 
RCAAP offers SaS hosting services for repositories (based on DSpace) and OA journals (based on OJS). Currently RCAAP hosts 27 repositories and 22 journals.
