Do I need an ORCiD to participate in this PLOS agreement?

No. However, registering for an ORCiD is recommended to assist the University of Miami in tracking your scholarly output. ORCiD (Open Researcher and Contributor ID) is a registry of unique identifiers for researchers and scholars that is open, non-proprietary, transparent, mobile, and community-based. ORCiD provides a persistent digital identifier to distinguish you from all other researchers. To learn more and to get your ORCiD please visit https://sp.library.miami.edu/subjects/ORCID .
