The virtual exhibition Ruhleben: a picture of a World War I internment camp has been created by the Harvard Law School Library, Cambridge, Mass,, with materials from two collections in its holdings, the Maurice L. Ettinghausen collection and the John C. Masterman collection which you can search with online findings aids. The exhibition shows the life of British civilian prisoners of war at the Ruhleben internment camp near Spandau on the outskirts of Berlin between November 1914 and November 1918. Ruhleben was the only German camp for civilian prisoners of war. The internees had very different backgrounds. There is relatively much documentation about the regulations and administration of the camp.
