This article examines how representations of genocide are contained within an archive. In considering those archives that follow and attempt to approach, record and respond to acts of genocide, I will focus on testimonial archives and the modes by which certain testimonies fail to be held or 'admitted' within the archive. Drawing on examples from the ICTY, as well as from the Domestic Court in Belgrade, I call for a rethinking of the aims and expectations of those archives that are charged with collecting testimony. I suggest that is that which is unrepresented in and excluded from testimonies presented in a legal setting, which disrupts the notion that archives might contain, conclude and comprehend an event of trauma. I argue that the very inaccuracy and the subjectivity of relevance within an archive is highlighted by that which is absent or elided.
