Travel the world and take a trip back in time with this colourful trailer highlighting rarely seen and oft-sun-soaked Central Office of Information films, newly digitised thanks to IWMs five-year preservation project Digital Futures. Shared across The National Archives and the British Film Institute’s social media platforms, as well as IWM's digital platforms, this trailer is part of this year's cross-collections collaborative project ‘COI 75’ (#COI75, #Collections United).

The Central Office of Information (COI) was created 75 years ago, producing films and campaigns to share key messages with the British population. In this post, Michelle Kirby (IWM Film Curator, Cold War/late 20th-century conflict), Sarah Castagnetti (TNA, Visual Collections), and Patrick Russell (BFI Senior Curator, Non-fiction) explain how they are teaming up for an ambitious new project showcasing highlights from their COI collections.
