Additional Information

Organizational History

The registry began as two, independent projects in 2011: one funded in the United States by the Institute of Museum and Library Services (IMLS) led by the Purdue University Libraries and another funded in Germany by the Deutsche Forschungsgemeinschaft (DFG) as a collaboration of the Berlin School of Library and Information Science, Helmholtz Open Science Office, and Karlsruhe Institute of Technology Library. These efforts merged into a single service under the auspices of DataCite, with which re3data has continued to work as a partner service. Further development was made possible with additional support from the DFG, Arnold Foundation, and European Commission in collaboration with the original project partners as well as DataCite, the American Geophysical Union, and other collaborators. Development of re3data continues through grant-funded and in-kind contributions.
