This talk examines the work of the USC Shoah Foundation Institute in consulting with the testimony-gathering efforts of the Documentation Center of Cambodia (DC-Cam), an independent Cambodian research institute compiling written records, photographs and video testimonies of the Cambodian genocide. The collaboration between these two institutions raises pressing questions concerning the limits and possibilities of documenting more recent and contemporary genocides by using methods of testimony that were originally developed for survivors and witnesses of the Shoah. This talk thus considers the challenges of examining genocides at large through the particular lens of the Holocaust.
