Hass is the author of Sacrificing Soldiers on the National Mall​ and Carried to the Wall. In Sacrificing Soldiers on the National Mall, she examines this war memorial boom, the debates about war and race and gender and patriotism that shaped the memorials, and the new narratives about the nature of American citizenship that they spawned. Carried to the Wall explores the restless memory of the Vietnam War and an American public still grappling with its commemoration. Hass contextualizes her study of this phenomenon within the history of American funerary traditions (in particular non-Anglo traditions in which material offerings are common), the history of war memorials, and the changing symbolic meaning of war.
