This volume, with 67 papers in total, consists of invited and contributed papers which were presented at the Inter- national Conference on Electron Diffraction held at Imperial College, London University, from 19 to 21 September 1977. As this conference was planned in celebration of the 50th Anniversary of the discovery of electron diffraction in 1927, it is natural that the book is entitled 'Electron Diffraction 1927-1977', although it contains little historical material. In the half-century since its discovery, electron diffraction has played an important and unique role in the study of the structure of matter, but it is also true that it has been accompanied by inherent theoretical difficulties due to the complexity of the process of electron scattering by
