This anthology of texts about what have been termed Structural Films attempts to bring together some of the more important essays and articles on those films which have formed the core of film work in this field since its inception. It is a first attempt to bring together texts from Europe, Britain and the United States, on films from Europe, Britain and the United States. In the past we have been inundated with the parochial, American view of avantgarde film work, as expounded on both sides of the Atlantic. This anthology was published to coincide with the series of eighteen programmes, Structural Film Retrospective, at the National Film Theatre, London, in May 1976.
