                                                  had the mission of contributing 
                                                  to shed more light on the buildings 
                                                  that served the purposes of 
                                                  illegal repression, as a means 
                                                  to prevent that through oblivion

                                                  is an ongoing task. The data-gathering 
                                                  and research carried out collectively 
                                                  with local individuals and organizations, 
                                                  has led us to design the maps 
                                                  we present today. These maps 
                                                  may be printed and used for 
                                                  pedagogical, study or legal 
                                                  investigation purposes.

                                                  a new and useful tool to identify 
                                                  the dimension of State terrorism 
                                                  in Argentina and understand 
                                                  the logic and the systematic 
                                                  nature of the repression. And 
                                                  also to recognize the task that 
                                                  still lies before us to build 
                                                  more precise and federal memory.
