ORCID provides two core functions:
ORCID makes its code available under an open source license, and will post an annual public data file under a CC0 waiver for free download.
The ORCID Registry is available free of charge to individuals, who may obtain an ORCID identifier, manage their record of activities, and search for others in the registry. Organizations may become members to link their records to ORCID identifiers, to update ORCID records, to receive updates from ORCID, and to register their employees and students for ORCID identifiers.
Author identities are a solution for uniquely identifying authors, who can publish under multiple names (including maiden names), have similar names and initials, and be cited in different ways with different citation styles. By connecting publications with these unique identities, authors can reduce ambiguity and ensure proper citation counts and other metrics, improving their research impact.
