Memory of Mankind (MOM) is a preservation project founded by Martin Kunze in Hallstatt, Austria, in 2012. Its main goal is to preserve knowledge about present human civilization from oblivion and collective amnesia. Information is printed on ceramic tablets and stored in the local salt mine. The project aims to create the "time capsule of our era", letting anyone participate by allowing them to submit texts and images. In contrast to national archives, content for MOM is collected by those who take part, and it constitutes a collective, "bottom-up" history.
