Anais Nin's diary was an underground literary sensation before it was ever published.
Volume 1 of Nin's diary, covering 1931-34, was published in the late 1960s when Henry Miller, her lover during the time period covered by this volume and Hugo Guiler, Anais's first husband (whom she never divorced) were both still alive. As a consequence, there are many omissions and edits for the sake of discretion. Those omissions were revealed when _Henry and June_, also taken from Nin's diaries, was published after the death of all protagonists.
Consequently, a volume that appears to be frank and honest upon a first reading looks somewhat less so when compared with the alternative version contained in _Henry and June_, which contains material expurgated from the first year of this volume. Confused yet?
The more Anais Nin slips away from us, the more we seek her. When reading this volume I come to believe that there is something to be said for Nin's position that she sought to portray a deeper psychological truth and the objective facts were less important.
