Henry and June: From the Unexpurgated Diary of Anaïs Nin (full title "Henry and June: From A Journal of Love: the Unexpurgated Diary of Anaïs Nin (1931–1932)") is a 1986 book that is based upon material excerpted from the unpublished diaries of Anaïs Nin.
Anaïs Nin (] ; born Angela Anaïs Juana Antolina Rosa Edelmira Nin y Culmell; February 21, 1903 – January 14, 1977) was an essayist and memoirist born to Cuban parents in France, where she was also raised.
 She spent some time in Spain and Cuba, but lived most of her life in the United States, where she became an established author.
 She wrote journals (which span more than 60 years, beginning when she was 11 years old and ending shortly before her death), novels, critical studies, essays, short stories, and erotica.
 A great deal of her work, including "Delta of Venus" and "Little Birds", was published posthumously.
Incest: From a Journal of Love: The Unexpurgated Diary of Anaïs Nin (1932–1934) is a 1992 non-fiction book by Anaïs Nin.
 It is a continuation of the diary entries first published in "Henry and June: From the Unexpurgated Diary of Anaïs Nin".
 It features Nin's relationships with writer Henry Miller, his wife June Miller, the psychoanalyst Otto Rank, her father Joaquín Nin, and her husband Hugh Parker Guiler.
 She also copied some of her correspondence with these people into her diary.
 Much of this book was written in English, although those of her letters which were originally written in French and Spanish were translated.
 Most of this diary takes place in France, particularly Clichy, Paris and Louveciennes.
The Diary of Anaïs Nin is the published version of Anaïs Nin's own private manuscript diary, which she began at age 11 in 1914 during a trip from Europe to New York with her mother and two brothers.
 Anaïs Nin would later say she had begun the diary as a letter to her father, Cuban composer Joaquín Nin, who had abandoned the family a few years earlier.
Fire: From the Unexpurgated Diary of Anaïs Nin (full title "Fire: From A Journal of Love: the Unexpurgated Diary of Anaïs Nin (1934–1937)") is a 1995 book that is based on material excerpted from the unpublished diaries of Anais Nin.
 It corresponds temporally to part of Anaïs Nin's published diaries, but consists mostly of material about her love life that was too sensitive or secret to publish in her lifetime or in that of others involved.
Nearer the Moon: From a Journal of Love (full title "Nearer the Moon: From a Journal of Love, the Unexpurgated Diary of Anaïs Nin (1937–1939)") is a 1996 book based upon material excerpted from the unpublished diaries of Anaïs Nin.
 It corresponds temporally to part of Nin's published diaries.
 It consists mainly of material that was left out of the published version because it would have hurt people involved or their relationships with Anaïs Nin had it been published at the time.
Collages, published in 1964, was Anaïs Nin's last published novel (excluding her erotica).
 It is very different from the previous novels of the "Cities of the Interior" series, because it contains none of the familiar characters in those novels.
 It is also different in that it takes place on two continents, has about two dozen important characters, and for the first time in Anaïs Nin's work the female lead is not seeking psychological wholeness.
 Most of Anaïs Nin's other novels only have a few main characters, there is rarely much geographical movement in the other novels, and usually the lead character is a woman seeking psychological wholeness.
Seduction of the Minotaur is an autobiographical novel by the mixed nationality writer Anaïs Nin, the last part of her "Cities of the Interior" sequence.
 It is about a woman named Lillian, and her self-psychoanalysis.
 The setting is taken from Anaïs' diary account of her first trip to Acapulco in 1947, and the novel repeats much of the first part of "The Diary of Anaïs Nin" volume V.
 Since the author was concerned with psychology rather than physical adventure, there is actually less violence in the novel than in the diary account.
 The exception is that the doctor allows himself to be shot because he is loved only as a doctor and never as a man, perhaps patterned after her understanding of Otto Rank's death.
Anaïs Nin: A Biography is Deirdre Bair's award-winning biography of writer Anaïs Nin.
 It is considered arguably by many to be the most comprehensive, well-researched, and scholarly biography available of Nin.
 Though the biography has received praise, it has also angered some fans of Anaïs Nin as well as some of her former associates, some of whom claim that Bair's critical and rigorous investigation of Anaïs Nin's life is unsympathetic.
