The presentation of the editor of the Military Technical Courier focuses on the experiences of the journal regarding sustainability of non-commercial open access. Being published by the state University of Defence in Belgrade, the journal has a stable funding source thus avoiding problems with sustainability. Its indexing in Redalyc is of great importance since it additionally provides free XML-JATS copies of journal’s articles which are compatible for exporting directly to the DOAJ database. The Editorial Office especially emphasizes the significance and usefulness of the Marcalyc system as well as the exceptional cooperation with the colleagues from Redalyc.
