ORCID is a nonprofit organization helping create a world in which all who participate in research, scholarship and innovation are uniquely identified and connected to their contributions and affiliations, across disciplines, borders, and time. In October 2012, ORCID launched its open registry of person identifiers for researchers and scholars. Since then, more than 4.7 million ORCID identifiers have been minted worldwide by individuals themselves. Over 850 global organizations worldwide have committed to incorporating iDs into their systems and workflows, and publishers and funders are starting to require iDs during submission. Research institutions represent the largest sector of ORCID members, though the connection of this sector to the others isn’t always understood. In this poster we will explain the overall ORCID ecosystem, and the important role that research institutions play, both in providing and gaining benefits.
