Nin's most studied works are her diaries or journals, which she began writing in her adolescence. The published journals, which span several decades from 1933 onward, provide a deeply explorative insight into her personal life and relationships. Nin was acquainted, often quite intimately, with a number of prominent authors, artists, psychoanalysts, and other figures, and wrote of them often, especially Otto Rank. Moreover, as a female author describing a primarily masculine constellation of celebrities, Nin's journals have acquired importance as a counterbalancing perspective.
