Norwood's 2009 book The Third Reich in the Ivory Tower: Complicity and Conflict on American Campuses, drew attention even before publication. According to Norwood, "Harvard was involved in active steps that helped legitimate the Nazi regime in the West,"  and was “indifferent to the prosecution of German Jews and indeed on numerous occasions assisted the Nazis in their efforts to gain acceptance in the West,” welcoming one of Adolf Hitler’s closest deputies to a reunion, hosting a reception for German naval officials and sending delegates to a celebration at a German university that had expelled Jews while failing to condemn the policies of Hitler’s National socialist regime.
Norwood's most recent book is Antisemitism and the American Far Left. This is the first systematic study of the American far left's role in both promoting and combating antisemitism. The book covers both the Old Left and New Left, including the latter's black nationalist allies. It also examines the antisemitism of the contemporary far left, including its relationships with Islamists.
