From the ORCID Blog:
To further support the uptake of ORCID, in 2017 Springer Nature engaged in a trial mandating ORCID identifiers for corresponding authors of primary research manuscripts at 46 journals across our portfolios.
The trial ran from April 27 for 6 months and the mandate was applied at different stages of the manuscript processing: 14 Nature-branded research journals required iDs at acceptance, while 10 BioMed Central (BMC) and 22 Springer journals did so at initial submission. Corresponding authors were able to share their ORCID identifier in the manuscript tracking system (via the ORCID API); without this step the submission would not proceed to the next stage.
A positive outcome
The response from the research communities was a positive one. There were no instances reported of authors who refused to provide an ORCID identifier at acceptance for the 14 Nature-branded journals, and no observable drop in submissions to the BMC and Springer journals participating in the trial that could be related to the mandate.
Given the success of this initiative, the trial did not end and is still ongoing for the journals that originally took part. In addition, Springer Nature is now looking to extend the mandate to more journals and evaluating whether to experiment with a mandate for contributing authors.
