If open access is the goal,
it takes a team to reach it!


Open Access Repository Ranking (OARR) is a research project initiated at the Information Management Department of Professor Peter Schirmbacher at the Berlin School of Library and Information Science (BSLIS), Humboldt-Universität zu Berlin (HU Berlin). The team members bring complementary skills to run and develop OARR. As open access advocates we share a passion to make a difference in the open access community. All of us are or were either affiliated with BSLIS or Computer and Media Service (CMS) at HU Berlin.

OARR cooperates with the Bielefeld Academic Search Engine (BASE) at Bielefeld University and is supported by the DINI working group on “Electronic Publishing“.
