EUR ORCID LibGuide: FAQ's & Tips

Enhance the discoverability and visibility of your research

I have more than 1 ORCID iD! How can I solve this?

ORCID has several controls in place to discourage more than one ORCID iD for a researcher. When you register, they check for duplicates based on the name and only one ORCID iD per email address is allowed. 

However, it is possible you have more than one ORCID iD. You can remove your duplicate ORCID iD:

  • Login to the ORCID record you want to keep
  • Click your name at the top of the page and choose Account Settings
  • Click Remove a duplicate record
  • Enter the sign-in details for the record you want to remove
  • Click Remove duplicate record

Please note: all information and permissions from the duplicate record will be deleted, and the associated email address(es) will be added to the primary record.

How can I add my publication list from my Google Scholar Profile?

When you have a Google Scholar Profile, you can download that list and upload it in your ORCID record.

Please note: Google Scholar has no article identifiers like DOI or PubMed ID. To make full use of ORCID, the records should have a DOI or another identifier.

Download your publication list from your Google Scholar profile

  • Open your Google Scholar Profile and log in
  • Mark the titles you want to export
  • Click Export
  • Choose BibTeX 
  • Save the file
  • Change the format from .txt to .bib

Upload the file in your ORCID record

  • Open your ORCID record 
  • Click + Add behind the Works header and select Add BibTeX
  • Click the button Choose BibTeX file to import and browse to the .bib file from Google Scholar
  • Check the records added - mark the publications you want to add and click Import work to your record

Some publications are twice in my ORCID record

If works are added from multiple sources or added manually, they are automatically grouped together when they have a common identifier, like a DOI. In your private ORCID record you will see 'Preferred source (of x)' at the bottom of the record. By default, the oldest versions is shown, but you can select another source, by clicking 'Make preferred source'. We advice to choose a source with a green checkmark, like Crossref or EUR & Erasmus MC Research Information Portal.

Article is added by 4 different sources to the ORCID record. Via Make preferred source you can choose the one that's visible.

If the works are not grouped together, because they have different or no identifiers, you can group them together manually:

  • Mark the works you want to group
  • When two or more works are marked the button Combine works at the top of the Works section in the Actions list becomes clickable.
  • The works will be displayed as one work. 
  • You can select the preferred source.

Names of co-authors

When you add a publication manually to your ORCID record, you can add co-authors via 'Add another contributor'. The name is required. You can add one or more contributor roles (also for yourself), by selecting a role from CRediT (Contributor Roles Taxonomy). It's not possible to add the ORCID iD of the co-authors.

How can I find the ORCID iD of a collaborator?

Sometimes you are asked to provide the ORCID iD of a collaborator, for example when creating a data management plan. The best way to add an ORCID iD is by authorizing a tool or publisher to ‘Get your ORCID iD’, but this is not always possible and only the owner of the ORCID iD can give this permission, you can’t do it on their behalf. If you can’t ask your colleague, you can search the ORCID registry.

To find the ORCID iD:

  • Go to the ORCID registry:
  • Use the search option at the top of the page
  • Enter the first name and last name (most researchers add their first name, but it's possible a researcher used one or more initials). 
  • If there are namesakes, use the Affiliations and Other names to make your selection. If no affiliation or other name is shown, you have to click the ORCID iD(s) to see more information in the ORCID record(s).
  • Check the ORCID record: are the works authored by your collaborator? Is there a bibliography or other information to be sure that that’s the ORCID iD of your collaborator?

If there is no public information in the ORCID record, then Crossref Metadata Search can be a workaround – there you can find publications that are linked to the ORCID iD, because the ORCID iD was used while publishing.

  • Go to Crossref Metadata Search:
  • Enter the ORCID iD (only the 16 digits, with the hyphens)
  • Check the results: are the publications written by your collaborator?

Of course, it’s possible the researcher has no ORCID iD yet!

Another username & password?!

You can sign in to your ORCID record with your ORCID iD or email address and the password you created. It's also possible to sign in with your EUR login credentials. 

  • Open the Sign in page of ORCID and click the button Access through your institution
  • Enter Erasmus in the Organization's name box
  • Select Erasmus University Rotterdam and click Continue
  • If you are not logged in yet, login with your ERNA ID and password 
  • The screen 'Link your Erasmus University Rotterdam account to your ORCID record' should appear
  • Enter your ORCID iD or email address and your ORCID password
  • Click Sign in and link your Erasmus University Rotterdam account

In your Account Settings, you can see the Alternate sign in Accounts. There is also the option to unlink the accounts.

If you want to login to your ORCID record, you can now use the Access through your institution option or your ORCID credentials.

Please note: creating this link doesn't send data from ORCID to any EUR system or vice versa.

You can also sign into ORCID using your Facebook or Google login, after linking the Facebook or Google account to your ORCID. 

Can I get help with getting my ORCID record up-to-date?

Yes! You can make an online appointment with the Erasmus Library ORCID Team. A team member will support you in adding publications to your ORCID record.


You can also request an ORCID Quick Scan: send your ORCID iD to and the Erasmus Library ORCID Team will check your ORCID record, especially the works, employment, funding, and peer review sections, and give personal recommendations on how to add information to your ORCID record as easily as possible.

QR code

It's possible to create a QR code - a machine-readable graphic - that links to your ORCID record. You can add it for example to a poster you present at a conference - visitors can scan the code with a QR code reader on their mobile phone and are redirected to your ORCID record. 

  • Sign into your ORCID record 
  • Click your name at the top of the page and choose Account Settings
  • Scroll to the end of the page 
  • Click Get a QR code for your ORCID iD
  • Click Click to download your QR code
  • A PNG file is created, save that file

Notification preferences

Under Account settings (accessible by clicking the arrow next to your name at the top of the page) you can set your notification preferences: when to receive information from ORCID. Open Email frequency and select how often you like to receive summary emails from ORCID. 

For the option 'ORCID members wanting your permission to automatically update your record' we recommend choosing one of the summary options, to make sure you will receive the request from Crossref for permission to auto-update your record.
