Early work

Le Guin's first published work was the poem "Folksong from the Montayna Province" in 1959, while her first published short story was "An die Musik", in 1961; both were set in her fictional country of Orsinia. Between 1951 and 1961 she also wrote five novels, all set in Orsinia, which were rejected by publishers on the grounds that they were inaccessible. Some of her poetry from this period was published in 1975 in the volume Wild Angels. Le Guin turned her attention to science fiction after a lengthy period of receiving rejections from publishers, knowing that there was a market for writing that could be readily classified as such. Her first professional publication was the short story "April in Paris" in 1962 in Fantastic Science Fiction, and seven other stories followed in the next few years, in Fantastic or Amazing Stories. Among them were " The Dowry of Angyar ", which introduced the fictional Hainish universe, and " The Rule of Names " and " The Word of Unbinding ", which introduced the world of Earthsea. These stories were largely ignored by critics.

Ace Books released Rocannon's World, Le Guin's first published novel, in 1966. Two more Hainish novels, Planet of Exile and City of Illusions were published in 1966 and 1967, respectively, and the three books together would come to be known as the Hainish trilogy. The first two were each published as half of an "Ace Double": two novels bound into a paperback and sold as a single low-cost volume. City of Illusions was published as a standalone volume, indicating Le Guin's growing name recognition. These books received more critical attention than Le Guin's short stories, with reviews being published in several science fiction magazines, but the critical response was still muted. The books contained many themes and ideas also present in Le Guin's better known later works, including the "archetypal journey" of a protagonist who undertakes both a physical journey and one of self-discovery, cultural contact and communication, the search for identity, and the reconciliation of opposing forces.

When publishing her story "Nine Lives" in 1968, Playboy magazine asked Le Guin whether they could run the story without her full first name, to which Le Guin agreed: the story was published under the name "U. K. Le Guin". She later wrote that it was the first and only time she had experienced prejudice against her as a woman writer from an editor or publisher, and reflected that "it seemed so silly, so grotesque, that I failed to see that it was also important." In subsequent printings, the story was published under her full name.
