This week we celebrated World Day for Audiovisual Heritage (27 October), which was set up by UNESCO to flag both the value and the fragility of these items.

Audiovisual material, films, recordings and moving images, hold shared memory, open up cultural conversation, and lets us follow how ideas, languages and communities change over time. Through these recordings we have access to events we didn’t live through, voices from the past, and places that no longer exist.
