Rabun Gap-Nacoochee School: Rabun Gap-Nacoochee School (informally known as Rabun Gap) is a small, private college preparatory school located in Rabun County, Georgia, United States, in the Appalachian Mountains.  It is both a boarding and a day school.  Rabun Gap is notable for initiating the "Foxfire" magazine project in 1966, experiential education based on interviewing local people, and writing and publishing articles about their stories and oral traditions.  This inspired numerous schools across the country to develop similar programs.

Foxfire (magazine): The Foxfire magazine began in 1966, written and published as a quarterly American magazine by students at Rabun Gap-Nacoochee School, a private secondary education school located in the U.S. state of Georgia.  At the time Foxfire began, Rabun Gap Nacoochee School was also operating as a public secondary education school for students who were residents of northern Rabun County, Georgia.  An example of experiential education, the magazine had articles based on the students' interviews with local people about aspects and practices in Appalachian culture.  They captured oral history, craft traditions, and other material about the culture.  When the articles were collected and published in book form in 1972, it became a bestseller nationally and gained attention for the Foxfire project.

The Headmaster (short story): The Headmaster is a short story by the British mystery and thriller writer Michael Gilbert about the counterspies Mr. Calder and Mr. Behrens.  First published in the United Kingdom in the June, 1962, issue of "Argosy", it was later published in the United States in "Ellery Queen's Mystery Magazine" and then collected in book form along with other stories about the same two protagonists as the sixth of eleven stories in "Game without Rules".  It is set in a contemporary, but undated London, and, unlike most of the other stories in this series, has Mr. Calder as the main character, with only brief appearances by Mr. Behrens and Rasselas, the Persian deerhound.  It is written in Gilbert's usual spare style, but with even fewer overtones and descriptions of the characters than are found in most of his works; the plot itself, and its resolution, is also somewhat unlikely, so the story, compared to the others in the series, must be considered a fairly minor one.  It does, however, have several examples of Gilbert's understated and astringent humor.

Sanshirō (novel): Sanshirō (三四郎 ) is a full-length novel by the Japanese writer Natsume Sōseki.

The Queen of Zamba: The Queen of Zamba is a science fiction novel written by L. Sprague de Camp, the first book of his "Viagens Interplanetarias" series and its subseries of stories set on the fictional planet Krishna.  It was written between November 1948 and January 1949 and first published in the magazine "Astounding Science Fiction" as a two-part serial in the issues for August and September 1949.  It was first published in book form as a paperback by Ace Books in 1954 as an "Ace Double" issued back-to-back with Clifford D. Simak's novel "Ring Around the Sun".  This version was editorially retitled Cosmic Manhunt and introduced a number of textual changes disapproved by the author.  The novel was first issued by itself in another paperback edition under the title A Planet Called Krishna, published in England by Compact Books in 1966.  A new paperback edition restoring the author's preferred title and text and including the Krishna short story "Perpetual Motion" was published by Dale Books in 1977.  This edition was reprinted by Ace Books in 1982 as part of the standard edition of the Krishna novels.  The novel has been translated into German, French, Italian, Czech, and Polish.  An E-book edition was published by Gollancz's SF Gateway imprint on September 29, 2011 as part of a general release of de Camp's works in electronic form.

Gnome Press: Gnome Press was an American small-press publishing company primarily known for publishing many science fiction classics.  Gnome was one of the most eminent of the fan publishers of SF, producing 86 titles in its lifespan — many considered classic works of SF and Fantasy today.  Gnome was important in the transitional period between Genre SF as a magazine phenomenon and its arrival in mass-market book publishing, but proved too underfunded to make the leap from fan-based publishing to the professional level.  The company existed for just over a decade, ultimately failing due to inability to compete with major publishers who also started to publish science fiction.  In its heyday, Gnome published many of the major SF authors, and in some cases, as with Robert E Howard's Conan series (published in six books from 1950 – 1955) and Isaac Asimov's Foundation series (published in three books from 1951 – 1953), was responsible for the manner in which their stories were collected into book form.
