One of the stellar Platinum Age science fiction writers -- rigorously aware of that Age's fantastic social science conventions to good effect, Le Guin struggled early in her career, works often rejected for "inaccessibility," which also plagued sister Platinum C.J. Cherryh's early publication attempts.
Incongruent that Le Guin loathed Google Books for its unilateral publication of intellectual property without creator consent, yet several of her essays on writing are most accessible there. Of note "Science Fiction and Mrs. Brown." (Explorations of the Marvellous: The Science and the Fiction in Science Fiction.Science Fiction at Large, periodical. Peter Nicholls, editor. Print. 1976; Le Guin, Ursula K. The Language of the Night. Putnam. 1979: pgs 101 - 120. Print.)
Mrs. Brown is Virginia Woolf and Le Guin's everywoman persona, sometimes everyman, everyperson. Also of note, Le Guin's literary craft analysis favorably compares to other stalwart writers' narrative theory texts, and standout, in that Le Guin speaks from a traditionally male-dominated bastion.
