The Holy Book of Psychoanalysis

Definitely the best book to discover what psychoanalysis and Freudian doctrine. Very simply, Freud outlines his doctrine (unconscious, repression, dreams, etc .. Oedipus complex). Reading is nice: Freud allows some touches of humor and explicit about its effective by examples.
Thus, this book is ideal to have a good solid overview of Freudian theories. After or not it accedes, but this is another question ...

Part 2: Contribution to the history of the psychoanalytic movement

I would say that this is a "logbook". Freud tells us the beginning of psychoanalysis (sound development with Charcot and Breuer), and it evokes its stigma because of his new ideas and finally it describes the development of psychoanalysis. It processes over the history of psychoanalysis of psychoanalysis itself. The book is interesting but not essential. I'm personally not go through.
