"Throughout the period when Freud wrote his major works, various translations and editions, differing widely in the accuracy of their texts and the quality of their content, made their appearance. Increasingly, as the body of Freud's work achieved command stature, the need arose for a definitive and uniformly authentic English language edition of all his writings. The Standard edition of the Complete Psychological Works of Sigmund Freud was undertaken to achieve this goal. The work is under the general editorship of James Strachey and he himself has made new translations of many of the writings ... The result is to place this edition in a position of unquestion supremacy over all other existing versions -- which are in fact rendered obsolete. 'An outline of psycho-analysis' is the last book that Sigmund Freud wrote. A masterpiece of clarity and conciseness, it has a unique value in relation to all of Freud's work, for it is both a manual for the layman on the fundamental tenets of psycho-analysis, and a summary of the principles arrived at after a lifetime of research and experiment in the science of psychology."
