Open access (OA), is considered to be the free, unlimited online access to all kinds of scientific research results. Thus, open access can be applied to all forms of published research, including peer and non-peer reviewed academic journal articles, conference proceedings, dissertations, book chapters and monographs.

Internationally, there are now two generally accepted ways of implementing Open Access:

• Gold Open Access, ie the publication in well-established scientific journals under the OA framework, while the Author PublicationPublication/Processing Charges (APC) can be covered through various resources,
• Green Open Access, ie the self-archiving of research material in open access repositories.

The Library and Information Center (LIC) of the National and Kapodistrian University of Athens (NKUA) supports both of the above-mentioned ways through the implementation of corresponding procedures:

• as far as the Gold OA is concerned, by providing discounts on the costs of publications for the  members of the academic community under the corresponding HEAL-Link agreements with specific Publishers,
• while for the Green OA, through self-depositing / self-archiving scientific publications in the corresponding "Scientific Publications, Research and Other Material" Collection of the Pergamos Institutional Repository, as well as with the publication of open access electronic journals.

In addition, the LIC, as a member of the Hellenic Academic Libraries Link (HEAL-Link), fully supports the actions of the Link to enhance Open Access in our country, with the aim of moving to a new and sustainable framework for scientific publishing, which can be beneficial to public research and educational institutions, while continuously promoting the benefit of the Greek scientific community.

HEAL-Link, through the Declaration on Open Access in Greece, expresses its concerns about the inadequacy of the current model of scientific publication and explicitly sets the initiatives it undertakes. The Declaration is supported and endorsed by the Ministry of Education and Religious Affairs, through the Minister Mr. Costas Gavroglou, after a meeting with the President of HEAL-Link Mrs. Theodora Ioannidou, on May 31st, 2018, at the Ministry of Education and Religious Affairs.
