ORCID is an organization that provides unique identifiers for researchers and links their work across different publications, grant applications, patents, and other research activities. It addresses problems of name ambiguity and ability to track a researcher's work across different name variations and databases. ORCID identifiers are being integrated into publication and grant submission workflows to automatically link researchers to their work. Over 370,000 researchers have created ORCID identifiers so far and many organizations are working on integrating ORCID into their systems to improve interoperability and reduce workload for researchers.
