Starting in January 2019, SciELO will only index articles with ORCID code  (unique identifier of authors). In view of this, we request that in the submission, all authors register their ORCID in, in addition to the other academic data provided.
The authors of papers already submitted or in process should also insert this data in its registration page, considering the possibility, for the most recent cases, of publication occurring in 2019 edition.
