The periodicity and number of articles published (eligible for inclusion in LILACS[1]) per year are indicators of editorial production flow and the relevance of the journal in the area in which it is inserted. For LILACS collection in Brazil, the following is recommended:
| Periodicity | Number of articles published per year | ||
| Minimum | Desired | Minimum | Desired |

Regardless of the periodic’s frequency, this information should always be updated on the ISSN portal.
