In 1967 Landis published The Abraham Lincoln Brigade, an account of the experiences of Americans who fought in the Spanish Civil War. The book was based largely upon the reminiscences of SCW veterans, which Landis collected via correspondence and on audiotapes (the latter comprise of the Arthur H. Landis Audiotape Collection). The year his book came out, Landis was awarded a medal by the Presidium of the Soviet Committee of War-Veterans for his "great contribution in the history of the struggle of the Internationalists against fascism on the battlefields of Spain."
