Since June 2021, ORCID* is mandatory for all authors when submitting to ESJ Journal. It is desirable that the ORCID contains the (current) institution as minimum information, so that each author can be clearly assigned via the ORCID in the metadata.
If ORCID, addresses or e-mail addresses are missing or incorrect, we reserve the right to reject such submissions due to formal errors.
*ORCID (Open Researcher and Contributor ID) should speed up the submission process. This unique identifier for authors is included as a mandatory field for all contributors in the submission tool.
