Information about researcher identifiers

As the number of publications from a scholar increases along the time, it is possible to find another researcher sharing the same surname and/or initials. Also, people could have signed their works or contributions under different names over time. This makes difficult to discover research activities in databases, scientific journals, institutional repositories, etc. and it may cause publications to be incorrectly attributed to a wrong author or researcher sharing the same name than the actual author. To overcome these ambiguity problems, several organizations and publishers have developed a system of unique research identifiers.






Open Researcher and Contributor ID (ORCID) is an open and non-profit project which has developed a unique identifier for authors/researchers. The objective is to guarantee the unequivocal distinction of the scientific and technical production of the researchers, and also to be an effective method to entangle the research activities referenced in different information systems. ORCID is a unique numerical identifier of 16 digits, it is independent and it is based on the ISO 27729:2012 standard. It is applicable to all disciplines, research sectors across borders. It connects researchers and research by incorporating ORCID identifiers into the workflow of scientific communication.


It is a global application system that allows users to register their records with other author identification systems (Scopus Author Identifier, WOS ResearcherID and Google Scholar).

Researchers can register with ORCID free of charge at:

Each author indexed in the Scopus citation database has an automatically generated numeric identifier that helps the identification of authors/researchers with identical or similar surnames and/or names or spelling variations, and it groups documents under the same identifier.

To check if you have been assigned with this identifier you must perform a query following this link, you must be authenticated:


It is possible to find different profiles in Scopus for the same author. These possible duplicities happen when you have been publishing with variants of the your name or with different institutional affiliations. To collect all the Scopus records in a single researcher profile, you can use the following wizard:

It allows to associate the personal profile of an author with all their activity in academic publications, whether as author, reviewer or journal editor; even though these publications are not indexed in Web of Science. Registration is free.

In order to create a Google Scholar profile you will need a Google account. Once you have configured your Google Scholar profile, you can add your publications either automatically based on the application suggestions, or manually.

Google Scholar ensure to collect all citations from researchers' publications under the same name. The profile includes the name, the selected keywords of research interests, the generated citations metrics and the citations (including the links to the cited articles).

 How to import/export records to ORCID


 Import records to ORCID

You can import the records of your publications from various sources:
  • Log in to your ORCID account.
  • Go to the "Works" section.
  • Click on "+ Add works" and then on "Search & link".
  • Follow the instructions that appear on the screen to send records from ResearcherID or Scopus to ORCID.

Note: This option is used to import any list of records in BibTeX format, such as the one generated by some CRIS, in the case of the University of Barcelona, the Curricul@ -SIRA application.


 From Google Scholar
  • Export the records from your account in BibTeX format and save the file.
  • Log in to your ORCID account.
  • Go to the "Works" section.
  • Click on "+ Add works" and then on "Import BibTeX" and import your file.
 From Scopus
You can export the records of your publications from Scopus to ORCID. Follow these instructions:
  • From your author profile of Scopus (Author details).
  • Click on "+ Add to ORCID" and continue.
  • Log in to your ORCID account.
  • Add Scopus publications in ORCID.
