RCAAP portal aims to collect, aggregate and index Open Access scientific contents from Portuguese institutional repositories.

RCAAP constitutes a single entry point for searching, discovery and recall of thousands of scientific and scholarly publications, namely journal articles, conference papers, thesis and dissertations, distributed by several Portuguese repositories. A list of the repositories aggregated in the portal is available in the Directory.
RCAAP portal is one of the main components from the project Repositórios Científicos de Acesso Aberto de Portugal. RCAAP project is an initiative from UMIC Knowledge Society Agency, developed by FCCN Fundação para a Computação Científica Nacional, with the technical and scientific collaboration from Minho University.

The current version of RCAAP portal was developed based on the search platform Apache Solr.
