The BT Digital Archives are recognised by Arts Council England and UNESCO as being of UK and international significance.
The collection documents the role that British Telecom and its predecessors have played in rolling out local, national and global communications.
The collection includes records, photographs and film dating back as far as 1846, when the UK's Electric Telegraph Company was formed. The development of the telegraph and the telephone are documented, alongside major recent milestones - such as communications satellites and fibre optic cables.
Over half a million photographs, documents and other digitised artefacts are available to users of this collection, which has been developed for academic study and wider use by the general public.
