What are Author Identifiers?

Author identifiers give you a way to reliably and unambiguously connect your names(s) with your work throughout your career, including your papers, data, biographical information, etc. This can be helpful in a number of ways:

  • Provides a means to distinguish between you and other authors with identical or similar names.

  • Links together all of your works even if you have used different names over the course of your career.

  • Makes it easy for others (grant funders, other researchers etc.) to find your research output.

  • Ensures that your work is clearly attributed to you.
