National Documentation Centre (EKT), is, by law, the competent authority for the development and maintenance of the National Archive of Ph.D. Theses, instituted in 1985 and operated by EKT since then. NA.Ph.D. collects, in digital form, doctoral dissertations awarded by Higher Education Institutions (HEIs) in Greece as well as Ph.D. Theses awarded to Greek scholars by foreign HEIs and certified by the Hellenic N.A.R.I.C. N.A.Ph.D. consists of two individual information systems, which are developed and operated by EKT:

I. Ph.D. Management System:  is used exclusively by the Secretariats of the Schools/ Departments of Greek academic institutions and Hellenic N.A.R.I.C. This system exclusively allows the authorized staff of both the Secretariats and the Hellenic N.A.R.I.C, as well as doctorate holders, to complete the submission process easily and directly, guiding them by successive steps.

II. N.A.Ph.D. Theses: is an information system – digital repository which contains all doctoral dissertations that have been collected.
