The Standard Edition of the Complete Psychological Works of Sigmund Freud is a complete edition of the works of Sigmund Freud, the founder of psychoanalysis. It was translated from the German under the general editorship of James Strachey, in collaboration with Anna Freud, assisted by Alix Strachey and Alan Tyson. The Standard Edition (usually abbreviated as SE) consists of 24 volumes, and it was originally published by the Hogarth Press in London in 1953–1974. Unlike the German Gesammelte Werke, the SE contains critical footnotes by the editors. This editorial material has later been included in the German-language Studienausgabe edition of Freud.
