Memory of the World: The treasures that record our history from 1700 BC to the present day

Cambodia. One photograph in the archives shows a young mother cradling a baby. It is an image that brings to mind countless others of the same subject – a mother and child – especially images of the Madonna and the Christ Child, the essence of serenity and spiritual grace.

But learning of the fate that met this particular mother and child can evoke an almost unbearable pain in the viewer – for these two individuals, after having been meticulously documented in this photograph, were taken out and killed, as were the other subjects of the photographs in the Tuol Sleng Genocide Museum archives. These documents form a historical record, to be sure, but they also deliver a powerful emotional charge – and remind us of things that never should be forgotten, or repeated.

World significance, provenance and authenticity, and rarity and uniqueness are key values when assessing the suitability of a nomination of documentary heritage for inscription on the UNESCO Memory of the World Register. However, we must never forget the reasons why documents are so important to us, and why we believe so passionately in their preservation.

The historical evidence that documents convey is one reason; others are the beauty and craftsmanship, or the technical innovations some documents display. The capacity of documents to engage our emotions and connect us to people and events in the past is another.

Archivists, librarians and museum curators who work with collections relating to Indigenous people can testify to the powerful emotions that flow when these people find their families mentioned in documents, or see photographs or film footage of their ancestors, or hear recordings of voices speaking their language.

Holy books and writings can also evoke strong emotional responses in members of particular faith systems. For a believer, a document associated with a saint or a prophet is not just a physical object; it possesses a spiritual power over and above its historical significance, or its value as an original, rare or unique item.

The popularity of exhibitions of documents indicates how compelling these can be in connecting people with the past. An exhibition curator explains why visitors flock to see displays of letters by writers, artists, scientists, philosophers, inventors, and political figures: ‘We see the writers’ words directly, unfiltered. The manuscripts give a sense of the authors’ daily lives, friendships, concerns and ambitions, their work and their leisure.’ Original music manuscripts can have the same emotional power, as the viewer sees the erasures, the corrections and the resolutions that lie behind a finished score. Even the pen strokes can convey the passion and intensity of composition. There are few objects of material culture that are more imbued with the personality of their originators than documents such as these.

It is the task of the UNESCO Memory of the World Programme to ensure that future generations will be able to access these documents and experience their emotional power, as well as to learn about the historical memories that they convey, or appreciate their beauty and craftsmanship.
