At the “Unlocking Sources – The First World War online & Europeana” conference more than 200 representatives from research and teaching, mediation of history and education came together at the Berlin State University on 30-31 January to discuss the possibilities and limits of digital access to material about the First World War and review – from different perspectives – the contributions which have been made in the past years. As part of the plenary, Steven Stegers shared the challenges and opportunities for the use of these digital collections in history education and introduced the work done by EuroClio on the development of the Historiana First World War Module within the EuropeanaCreative project.
