An Archival Research Guide created in the project "Collaborative EuropaN Digital ARchive Infrastructure" CENDARI. The subject “Science and Technology in the First World War” has so far been treated from the perspective on inventions and the development of new weapons, and often the focus has been on the topic of chemical warfare at the expense of other important dimensions. The approach of this Archival Research Guide, by contrast, comes from the social sciences and focuses on the establishment of relevant scientific, military and governmental bodies and on the personal networks established during the war.
