“Ergani” digital repository, 200 years of local history


The digital repository of the historical archive of the Aegean “Ergani” ( was recently launched, preserving more than 1.500 files that illustrate life in the last two centuries in the north-eastern Aegean. It was developed by the National Documentation Centre of Greece (EKT) in cooperation with the historical Archive of the Aegean “Ergani”, a non-profit organisation founded in 2002 and based in Mytilene, the capital of Lesvos.

“Ergani’s” rich archival collections include rare documents, photographs, amateur films from the 1930s, diaries, personal and business correspondence, ads, industrial designs, drawings and scientific reports. They vividly showcase daily life and the development of the olive oil industry on the island of Lesvos during those years of socio-economic and political change.

Historians, researchers, students, visitors to and residents of the NE Aegean and those interested in historical and ethnographic content can access documented archival records. The Repository offers dynamic search functions, registration and profile personalization and access to full metadata records and digital objects.

The archive is named “Ergani” after an internationally recognised and patented olive collection machine invented by Mitsas Kourtzis in 1924. The invention was innovative for its time and got recognition not only in Greece, but in other Mediterranean countries, where olive oil production is a core industry. It was presented in various international conferences and international journals of its time. Special place in the archive holds the Kourtzis family archive, a unique testimony that spans 4 generations of local entrepreneurs.

The repository is an integrated information platform for the management and showcasing of Ergani archival collections. It offers access to organized and documented archival material with the aim of facilitating historical research of the socio-economic developments in the NE Aegean during the 19th and 20th centuries.

The archival collections were documented using internationally recognized metadata schemas and incorporating authorities for types, subject headings, people, corporate bodies and families, ensuring easy access to information and inter-operability.

 “Ergani” aims to preserve and showcase Greek cultural heritage represented in the Archive. That is why it invests in improving its archive management infrastructures and know-how, applying the latest methodology in preservation, research and documentation of local archives and participating in international forums on digital heritage.

The “Ergani” Repository was developed within the Project "National Information System for Research and Technology /Social Networks-User Generated Content" (NISRT). NISRT is co-financed by Greece and the European Union - European Regional Development Fund (Operational Programme "Digital Convergence", NSFR)  ( ).

The National Documentation Centre develops Repository Services for Greek cultural and scientific institutions. These services are being further evolving, combining Software as a Service (SaaS) and Cloud Computing technologies, in order to develop a sustainable ecosystem for the management and delivery of authoritative digital content.
