The National Collective Catalog of Scientific Journals (ESKEP) of the Greek scientific and technical libraries is a service that the National Documentation Centre (EKT, in Greek) develops, maintains and offers within its institutional scope.

The National Archive of PhD Theses (EADD) provides access to the PhD theses from all Higher Education Institutions (HEIs) in Greece, as well as the PhD theses awarded to Greek scholars by foreign HEIs and certified by the Hellenic NARIC.

The meta-search engine Muse-Search allows the simultaneous search in e-resources of the Greek Academic Libraries Link, in the Union Catalog and in selected webpages.
