The history of Lviv in wartime has been intensively studied, especially since the collapse of communism when the large Soviet archival collections became available to historians.
Christopher Mick provides a first-class account of the city history in 1914-1945. The city is discussed also in the more general studies of the Soviet occupation of the Western Ukraine by Jan Gross, and of Nazi destruction of Galician Jews by Dieter Pohl. John-Paul Himka describes and analyzes in details the story of the anti-Jewish pogroms of June 30, 1941, while Polish and Ukrainian scholars focus on the NKVD massacre of the (mostly but not exclusively) Ukrainian prisoners and the Nazi execution of Polish professors.
The Lviv war experience is also present in two influential syntheses of mass violence by Timothy Snyder, Bloodlands and Black Earth.
