The ‘Memory of the World’ (MOW) is the recorded collective legacy of the peoples of the world and represents a significant proportion of the world's heritage of human achievements since the dawn of time. While some of this is transmitted orally, in its recorded form it is more commonly known as 'documentary heritage'. But it is fragile, subject both to natural deterioration and man made disasters. UNESCO's MOW programme, launched in 1992, aims to (1) preserve such materials; (2) provide access through digitization, book publication, etc.; (3) raise global awareness of the significance of documentary heritage. This last is carried out principally through the identification of significant documentary heritage and listing it on a MOW register, whether International, Regional or National. Nominations for inscription can be made by any individual or body and an International Advisory Committee meets every two years to make decisions on entries in the register. In addition there is a structure of regional and national committees but this is incomplete and needs to be strengthened.
