Question: Girlfriends and Asimov's Science Fiction, are which type of publication?
Context: "The Deep" is a science fiction novelette by American writer Isaac Asimov.  It was written in July 1952 and first published in the December 1952 issue of "Galaxy Science Fiction".  The story subsequently appeared in the Asimov collections "The Martian Way and Other Stories" (1955) and "The Best of Isaac Asimov" (1973).  In "In Memory Yet Green", Asimov wrote that his motive in writing the story was to deliberately test whether one could do "anything" in science fiction, so he invented a society in which mother love was considered obscene. "Robbie" is a science fiction short story by American writer Isaac Asimov.  It was his first robot story and writing commenced on June 10, 1939.  It was first published in the September 1940 issue "Super Science Stories" magazine as "Strange Playfellow", a title that was chosen by editor Frederik Pohl and described as "distasteful" by Asimov.  A revised version of "Robbie" was reprinted under Asimov's original title in the collections "I, Robot" (1950), "The Complete Robot" (1982), and "Robot Visions" (1990).  "Robbie" was the fourteenth story written by Asimov, and the ninth to be published.  The story is also part of Asimov's "Robot" series, and was the first of Asimov's positronic robot stories to see publication. "Time Pussy" is an early science fiction short story by American writer Isaac Asimov.  It was the third of three stories Asimov wrote for John W. Campbell for a new category of science fiction tall tales in "Astounding Science Fiction" called "Probability Zero".  Campbell rejected the first two stories, "Big Game" and "First Law", since they were not what he was looking for, but he accepted "Time Pussy", albeit unenthusiastically.  Campbell also wanted to run the story under a pseudonym, since he wanted to encourage new writers to write "Probability Zero" stories.  Asimov agreed, and chose the name George E. Dale at random.  The story appeared pseudonymously in the April 1942 issue of "Astounding" and was reprinted under Asimov's name in the 1972 collection "The Early Asimov". "For the Birds" is a science fiction short story by Isaac Asimov.  The editor of a proposed fashion magazine wanted a science fiction story about a clothing designer.  Asimov agreed, and wrote the story in November 1978.  It was accepted, but the proposed magazine never appeared, and Asimov sold the story to "Asimov's Science Fiction".  "For the Birds" was published in the May 1980 issue of "Asimov's", and was reprinted in the 1983 collection "The Winds of Change and Other Stories".  The story was one of three Asimov wrote in the late 1970s set among a series of O'Neill-type space habitats. "Marooned off Vesta" is a science fiction short story by American writer Isaac Asimov.  It was the third story written by him, and the first to be published.  Written in July 1938 when Asimov was 18, it was rejected by "Astounding Science Fiction" in August, then accepted in October by "Amazing Stories", appearing in the March 1939 issue.  Asimov first included it in his 1968 story collection "Asimov's Mysteries", and subsequently in the 1973 collection "The Best of Isaac Asimov". "Reason" is a science fiction short story by American writer Isaac Asimov, first published in the April 1941 issue of "Astounding Science Fiction" and collected in "I, Robot" (1950), "The Complete Robot" (1982), and "Robot Visions" (1990).  It is part of Asimov's "Robot" series, and was the second of Asimov's positronic robot stories to see publication. Girlfriends was a women's magazine that provided critical coverage of culture, entertainment and world events from a lesbian perspective.  It was founded by Jacob Anderson-Minshall, Diane Anderson-Minshall and Heather Findlay.  It also offered relationship, health and travel advice.  Published monthly from San Francisco since 1993, it was distributed nationwide by Disticor.  It had the same publisher as lesbian erotica magazine "On Our Backs", but distanced itself from its pornographic counterpart by refusing to carry sexual ads.  "Girlfriends" magazine ceased publication in 2006. Asimov's Science Fiction (ISSN 1065-2698) is an American science fiction magazine which publishes science fiction and fantasy named after science fiction author Isaac Asimov.  It is currently published by Penny Publications.  From January 2017, the publication frequency is bimonthly (six issues per year). "The Imaginary" is a science fiction short story by Isaac Asimov.  It first appeared in the November 1942 issue of "Super Science Stories" and was reprinted in the 1972 collection "The Early Asimov".  Following the sale of "Half-Breeds on Venus", which was a sequel to "Half-Breed", Asimov suggested to "Astounding Science Fiction" editor John W. Campbell that he write a sequel to the story "Homo Sol".  Campbell was unenthusiastic, but agreed.  Since "The Imaginary" lacked the human-alien conflict that he had liked in the earlier story, Campbell ultimately rejected it.  "The Imaginary" was the twenty-first story written by Asimov, and the twenty-ninth to be published.  Due to the peculiar workings of the science fiction magazine publishing industry, "The Imaginary" appeared a month after the third story in the Homo Sol Trilogy, "The Hazing". "The Last Question" is a science fiction short story by American writer Isaac Asimov.  It first appeared in the November 1956 issue of "Science Fiction Quarterly" and was anthologized in the collections "Nine Tomorrows" (1959), "The Best of Isaac Asimov" (1973), "Robot Dreams" (1986), the retrospective "Opus 100" (1969), and in "Isaac Asimov: The Complete Stories, Vol.  1" (1990).  It was Asimov's favorite short story of his own authorship, and is one of a loosely connected series of stories concerning a fictional computer called Multivac.  The story overlaps science fiction, theology, and philosophy.
