Letters as a study of the history of personal stories/fates. The Warlux project aims to collect the personal war experiences of men and women who were conscripted into labour and/or military service by the Nazi occupation administration during the Second World War in Luxembourg. In order to present the individual perspective and the personal impact of the war at the front, in the labour camps and at home, we have collected over 5000 letters and diaries from the families concerned via an appeal for donations in 2021. The letters all need to be organised, structured and read. Digital tools such as scanners and text recognition help historians prepare the letters for analysis.
