This introduction situates the articles in this journal issue within recent scholarship about war and memory. The plethora of available terminology is addressed, tracing memory studies back to the rediscovery of Maurice Halbwachs’s theories of collective memory and its growth from the late 1980s, particularly in Holocaust Studies. The importance of studying war and memory now is highlighted, drawing attention to the current European and global tensions that have their roots in earlier twentieth-century conflicts. Brief synopses are offered of the issue’s articles, which discuss First World War novels; Lee Miller’s concentration camp photographs; 1960s Italian television programmes about the Holocaust; the Norwegian ‘Heavy Water Raids’; and post-1989 Rough Guides to Poland.
