This article explores the use of the UNESCO Memory of the World programme in claims for recognition of atrocities, focusing on two recent nominations: Documents of Nanjing Massacre and Voices of the ‘Comfort Women’. We argue that amid domestic and international contestation of memories and historical accounts, cultural programmes, such as the Memory of the World, have become increasingly politicised and used to push for international recognition of past atrocities. The article reflects on the character of the Memory of the World programme and the core reasons for nominations to such programmes. It also considers the possible consequences of registration as it transposes the heritage of memory from the local to the global stage (and back) and in the process subjects both memory and heritage to various forms of authorised transformation and reification. We bring attention to how official recognition by the Memory of the World affects ongoing collective memory formation, and express concerns about the appropriation of individual and local memories, as they are granted universal value.
