Researcher Identifier or How to Increase Your Visibility

Source : (CC0 Creative Commons)Also called a persistent digital identifier (PDI)  or permanent identifier, this unique, digital author identifier is a univocal way to identify a researcher, for example in a database or an institutional repository.

You should create a persistent digital identifier to:

  • Avoid the confusion of names between homonyms or ensure continuity in the event of a name change or variation in the researcher's name
  • Associate your publications with your profile even when you publish under different institutions
  • Manage your publication list
  • You can use it as a promotion tool to make your research outputs more visible and improve your research impact
  • Easily access the metrics of your publications (depending on the tool you choose to use)
  • Save time by not having to enter personal information multiple times. Possibility to extract your references for grant applications, for example

Always check the Terms & Conditions for each tool to find out who can access your data, if you can easily delete your account, etc.

ORCID (Open Researcher and Contributor ID) is a non-profit organisation (independent of publishers or databases)

It provides a free unique persistent digital identifier

Keep in mind:

  • It is free and available to any researcher in any discipline
  • It can be used by publishers, universities, repositories, research societies, funding agencies, etc.
  • ORCID users can manage their own visibility settings
  • You can link your ORCID ID to other IDs like Scopus Author IDResearcherID on Publons, etc.
  • ORCID does not offer metrics but you can connect your ID to Kudos and ImpactStory to generate your personal metrics profile
