This article approaches the question of teaching history through students´ books or school manuals. Recognizing the importance of the role of history as a builder of collective memory, the study analyses specifically the proposal of a manual (designed by the authors of this article) created for teachers and students about the Holocaust problematic and its treatment in Argentinean classrooms. Based on the material elaborated by CEANA (Comisión para el Esclarecimiento de las Actividades Nazis en la Argentina / Commission for the clarification of the Nazi activities in Argentina,) the Manual gives a new meaning to the Shoah´s history and memory and offers a new proposal of transference of this knowledge in the classroom to make it possible to teach a living and critical history that is in a permanent relationship with the present.
