Is that normal?
Those superscript numbers and links next to the authors' names (like the ones pointing to #ORCID, #Google Scholar, and #Scopus in the photo) serve as digital identifiers and profile links for the researchers.
Academic journals use these links for several important reasons:
* Disambiguation: Many #researchers share the exact same name. A unique identifier (like an ORCID ID or Scopus Author ID) ensures that papers are correctly attributed to the right person, preventing confusion between authors with similar or identical names.
* Academic Profiles & Metrics: They allow readers, editors, and institutions to quickly click through to view the author's complete publication history, citation counts, and overall research impact.
* Transparency and Verification: They prove the identity and institutional affiliation of the authors, adding credibility and authenticity to the published research.
* Networking and Collaboration: Other researchers can easily find how to contact or follow the work of specific authors in their field.
