The Greek PhD theses Online: Access to 29.000 PhD theses at


A valuable resource of scientific knowledge, the National Archive of Greek PhD theses, is now accessible at The portal’s new edition encompasses advanced functions for navigating and searching through several thousands of PhD theses and provides a series of additional services to registered users. The portal hosts the National Archive of PhD theses (EADD), which provides access to the PhD theses from all Higher Education Institutions (HEIs) in Greece as well as PhD theses awarded to Greek scholars by foreign HEIs and certified by the Hellenic NARIC.

The National Documentation Centre of Greece (EKT) is the organization responsible, by law, for the collection, development and maintenance of the National Archive of PhD Theses. The principle of open access to knowledge and research results lies at the heart of the repository’s creation and development.

The repository of EADD contains more than 29.000 bibliographic records of PhD theses (4.500.000 digitized pages) which have been systematically documented. Today, users can access the full text for more than 20.500 PhD theses. This number is continuously rising. Metadata records include core library catalog elements such as title, abstract, author, scientific field, educational institution, committee members, year of award, key-words, country, and language. Users may search the repository for the material they are interested in, or they may navigate through scientific fields, institutions, authors, countries, languages, dates.

Besides being able to browse through the pages and print the file per page, registered users can also download and save a thesis in pdf format. The process of registration takes only a few minutes and it is an essential process to safeguard that users download the file for personal use and not for any commercial reasons. Registered users may also order a thesis online and receive it in print and digital form (CD/DVD) or -in the case that the text is not available in digital form-, they may express their interest for the digitization of the full text of a thesis. A Helpcenter operates to support users by responding to their online requests and provide useful information and guidance (e.g. Frequently Asked Questions, Useful files).

The National Archive of PhD theses is a service provided by the National Documentation Centre of Greece (EKT). Since 1985, EKT is the institution officially responsible for the collection and maintenance of the National Archive of PhD theses. Until today, the institution aims at fully exploiting the potential of Information and Communication Technologies (ICTs) for the benefit of research and innovation.

For their most part, the theses included in the repository were completed from 1985 and onwards, and only a small percentage (about 6% of them) were awarded during the period 1932-1985. The complete official archive in print (more than 30.000 PhD theses) is being kept in the Library of Science and Technology at the National Hellenic Research Foundation (NHRF).

Recently, EKT updated the Archive with advanced functions and tools which ensure interoperability with other repositories and international e-infrastructures. Being an active member of DART-Europe -a partnership of research libraries and library consortia who are working together to improve global access to European research theses-, EKT contributes metadata to the DART-Europe Portal with an aim to support the management, discovery, usability and preservation of e-theses.

The updated edition of has been developed in the framework of the project "National Information System for Research and Technology- Social Networks and User Generated Content” (Operational Programe "Digital Convergence") which is the core project of the National Documentation Centre of Greece.
