Those wishing to have their paper included in the Conference Proceedings should submit completed research papers in Greek or in English, until 30 November 2026, through the platform of the National Documentation Centre. All papers will go through the double-blind review system. The Proceedings of the 4^th Conference will be published online through the ePublishing service of the National Documentation Centre (https://eproceedings.epublishing.ekt.gr/), as was the case with the publication of the Proceedings of the 1^st, 2nd and 3^rd Conferences (Proceedings available at: https://eproceedings.epublishing.ekt.gr/index.php/inoek). It should be noted that, at the authors’ responsibility, any paper submitted for publication in the Conference Proceedings through the ePublishing service is excluded from the possibility of being published elsewhere.
