ORCID

ORCID (Open Researcher and Contributor ID) is an open, non-profit, publisher-agnostic community-based effort to provide a registry of unique researcher identifiers as well as a transparent method of linking research activities and outputs to these identifiers. ORCID is unique in its ability to reach across disciplines, research sectors, and national boundaries and its cooperation with other identifier systems. 

An ORCID iD is a personal, persistent identifier and will travel with you over your entire professional career. Your ORCID iD is a 16-digit number randomly assigned by the ORCID registry. An example ORCID identifier would have the following structure: 0000-0000-0000-0000. It can be expressed as a URL like this: http://orcid.org/0000-0000-0000-0000.

Registering for an ORCID is free, and only takes a few minutes.
