The virtual exhibition 100 Jahre Erster Weltkrieg [100 Years First World War] has been created in 2014 by the Österreichisches Staatsarchiv in Vienna. You can search among 24 thematic collections which cover many aspects of the First World War and its immediate aftermath. You can look at a chronology for military and diplomatic events, at milestones in daily life and documents related to them, or compare the diary entries of Karl Schneller, an influential officer in the Austrian army staff (Armeeoberkommando (AOK)), and emperor Franz Joseph for a specific date. The exhibition can only be viewed in German.
The portal Wartime Canada has been created by a team of the University of Western Ontario as an educational resource for teaching the history of Canada during both World Wars by using documents and artifacts to get closer to actual experiences. The resources at this portal are organized by ten category headings with a verb, such as Fighting, Eating, Relaxing, Remembering and Worshipping. The selection of themes under these headings is very wide and instructive. The section on education gives guidance to larger subjects such as the war effort, government and economy, identity and culture, historical inquiry and society. For each theme you can set the selection of items to either the First or the Second World War by choosing this period from a dropdown box. The portal can be visited in English and French.
The digital version of the Kriegstagebuch Fridolin Mayer is an initiative of the Erzbischöfliches Archiv, Freiburg im Breisgau. Mayer (1877-1956) was a Catholic priest who served as a volunteer at several front locations in France. In 1918 he served briefly as a chaplain for prisoners of war in Switzerland. The archdiocesan archive at Freiburg holds the original manuscript (EAF Ha 595) and a typescript made in 1927 (EAF Na 16/1). The diary entries are published in blog fashion in chronological order. For each day of the diary a post will be created. The digital version is only accessible in German.
