Open Researcher and Contributor ID (ORCID) is a persistent digital identifier for researchers. Registering for an ORCID identifier is free and easy. Once you have your unique ORCID identifier, you can create a profile and/or link it to your other author IDs and profiles (e.g., ResearcherID, My NCBI, LinkedIn). You can associate existing publications with your ORCID profile by importing from sources like Scopus and Web of Science. Going forward, use your ORCID identifier in all stages of your research workflow (grant applications, manuscript submissions, etc.) to make sure that you get credit for your work.
