Persistent digital identifier systems are quickly becoming required elements of the research landscape. These identifiers are already being used for research articles and data products using digital object identifiers. ORCID provides a persistent digital identifier (an ORCID iD) that individual researchers may own and control, which distinguishes them from every other researcher. The iD can be connected with professional information — affiliations, grants, publications, peer review and more. It can be used to share information with other systems, ensuring researchers get recognition for all of their contributions, saving time and hassle and reducing the risk of errors.
