The digital collection Feldpost aus dem Ersten Weltkrieg [Letters from the front during the First World War] has been created by the Museumsstiftung Post und Telekommunikation (MFK) as a part of their online letter collections (Briefsammlungen). This collection contains some 700 letters written by soldiers during the First World War, a selection from the holdings kept at the Museum für Kommunikation Berlin, a branch of the MFK. Letters were subject to censorship, but nevertheless they formed a vital connects between the fronts and the home front. You can search the collection by themes, geography and sets (Konvolute), filter by dates (Zeitraum) or enter search terms in the free text search field. The online collection gives you transcripts of the letters. They can be read in connection with the volume Schreiben im Krieg / Schreiben vom Krieg [Writing in wartime, writing about war]. The collection can only be viewed in German.
