ORCID provides a persistent digital identity that allows researchers and authors to identify their work from those of others with the same or similar names. You will create and manage your ORCiD profile within your researcher profile in CRO. Your publications in CRO can be automatically uploaded into your ORCID profile.
ORCID does not provide citation metrics, but an ORCID can be used when you submit papers for publication or apply for grants. It aims to be the de facto standard for author identification in academic publishing and has a broad support base, with members including Elsevier, Springer, Wiley, Nature Publishing Group and Thomson Reuters.
