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