In August 2012 re3data.org – the Registry of Research Data Repositories went online with 23 entries. Two years later the registry provides researchers, funding organisations, libraries and publishers with over 1,000 listed research data repositories from all over the world making it the largest and most comprehensive online catalog of research data repositories on the web. re3data.org provides detailed information about the research data repositories, and its distinctive icons help researchers easily identify relevant repositories for accessing and depositing data sets.
To more than 5,000 unique visitors per month re3data.org offers reliable orientation in the heterogeneous landscape of research data repositories. An average of 10 repositories are added to the registry every week. The latest indexed data infrastructure is the new CERN Open Data Portal: http://service.re3data.org/repository/r3d100011381
