Back in 1973 and 1975 when the Internet was in its infancy the two Wells Reports recommended the setting up of a national university network in the UK. This book presents the definitive history of JANET, from the Flowers Report of 1965 that led to the setting up of the Computer Board through to the unveiling of the SuperJANET5 backbone in 2006 that finally realised the SuperJANET goals.
