From JISC:

BT has teamed up with Coventry University and The National Archives to create a searchable digital resource of almost half a million photographs, reports and items of correspondence preserved by BT since 1846. The project has been funded by Jisc, which provides digital services for UK education and research.

The remarkable collection showcases Britain’s pioneering role in the development of telecommunications and the impact of the technology on society, and will be freely available to the public under a Creative Commons licence to encourage sharing and the use of the material in school curricula and for research.


Users anywhere in the world will be able to log on to and explore 50 terabytes worth of images and documents detailing how Britain laid the foundations for global telecommunications, including  the first telephone exchange in 1879 and the Queen making the first automatic long distance telephone call in the fifties.

  • Documents relating to BT’s ancestor company, the Electric Telegraph Company, which in 1846 became the first nationwide communications company in the world
  • A letter from 1877 from Alexander Graham Bell’s agent offering Bell’s telephone to the British government – who turned it down
