A new beta service has been launched for searching and claiming works in DataCite:
With this tool, created in the context of the ODIN Project, authors can identify themselves with their ORCID ID and search their own works in the DataCite Metadata Store. They can add them to their research outputs in their ORCID profile. This new service also provides formatted citations in several popular citation styles, supports COinS, links to related resources, and displays the attached Creative Commons license where this information is available.
