The BT Digital Archives is our online research resource, the result of a £1 million collaboration between BT Heritage, Coventry University and The National Archives to digitise a core part of BT’s archive collection from 1846, almost half a million photographs, reports and items of correspondence preserved by BT over the past 167 years. The remarkable collection – which is recognised by UNESCO and Arts Council England as being of international importance – showcases Britain’s pioneering role in the development of telecommunications and the impact of the technology on society, and is freely available under a Creative Commons licence to encourage sharing and the use of the material in education curricula and research. Users anywhere in the world can explore 50 terabytes worth of images and documents detailing how Britain laid the foundations for global telecommunications.

Not all of our archive is digitised by any means. Combined with the public catalogue of our whole collection BT Digital Archives provides an introduction to the wider collection which is available to researchers at the BT Archives in London.
