I've recently finished the original Introductory Lectures on Psychoanalysis and am now reading the New Introductory Lectures. Planning on following these up by reading his Outline of Psychoanalysis which was not entirely completed by the time of Freud's death. I'm wondering what sections remained incomplete, and if there is much - in terms of the fundamentals of his theory - that I will still be missing having read the Outline and the (New) Introductory Lectures.

EDIT: If there are significant parts of Freud's theory that were intended to be included in the Outline of Psychoanalysis that I will be missing still having read these texts, then what should I read to fill in the gaps?
