The DART-Europe is a partnership of research libraries and library consortia across Europe, which are working together to promote global access to European Research theses in Europe. DART Europe encourages the creation and use of European e-theses and maintains a single European portal of Electronic theses and dissertations, to improve the management, usability and preservation of Electronic Theses and Dissertations. This initiative is supported by LIBER (Ligue des Bibliothèques Européennes de Recherche) and it is the European Working Group of the NDLTD (Networked Digital Library of Theses and Dissertations). The National Documentation Centre (EKT) is a partner for DART-Europe and it develops the repository for Greek PhD theses, which feeds DART.
