Holocaust museums record and memorialize deeply affecting historical events. They can nevertheless be described and criticized using standard categories of museum analysis. This paper departs from previous studies of Holocaust museums by focusing not on ethical or aesthetic issues, but rather on ontological, epistemic, and taxonomic considerations. I begin by analysing the ontological basis of the educational value of various objects commonly displayed in Holocaust museums. I argue that this educational value is not intrinsic to the objects themselves, but rather (...) stems from the extrinsic relations established between objects in museum exhibitions and displays. Next, I consider the epistemic, or knowledge-creating, function of Holocaust museums. I argue that the structure of public displays in such museums reflects the particular, document-based epistemology that continues to characterize Holocaust historiography and other fields of Holocaust research. Finally, I turn to examine taxonomic features of Holocaust museums. As I explain, both professional and ‘artefactual’ networks link the activities and display strategies of national, regional, and local Holocaust museums. A brief conclusion sketches some implications of my analysis for ongoing debates about the ethical function of Holocaust museums. (shrink)
