More Tomorrow & Other Stories is a collection by British author Michael Marshall Smith.  It draws together 30 of the author's short stories, including several written specifically for this book.  Smith's short stories had been partially collected in 1999's "What You Make It", but this had only been published in the UK.  "More Tomorrow & Other Stories" represented the first time that the stories had been published for the American market.  In addition to the extra stories, it features an introduction by Stephen Jones and an afterword by Smith. Tales of Pain and Wonder is Caitlín R. Kiernan's first short story collection.  The stories are interconnected to varying degrees, and a number of Kiernan's characters reappear throughout the book, particularly Jimmy DeSade and Salmagundi Desvernine.  The stories run the gamut from dark fantasy ("Rats Live on No Evil Star" and "Estate") to ghost stories and supernatural horror fiction ("Angels You Can See Through" and "Anamorphosis") to noir fiction ("Breakfast in the House of the Rising Sun" and "Lafayette").  A number of the stories have a decidedly H. P. Lovecraftian flavor and the influence of Charles Fort, as does much of Kiernan's fiction published since "Tales of Pain and Wonder".  The stories are also united by a theme of cultural decay and loss of meaning in 20th-century society, as expressed by the collection's epilogue, Kiernan's only published poem, "Zelda Fitzgerald in Ballet Attire."  Originally published in 2000 as an expensive limited-edition hardback by Gauntlet Publishing, it was reissued in trade paperback format in 2002 by Meisha Merlin Publishing.  In 2008, Subterranean Press re-issued the book again, in a limited edition hardcover, with a new author's introduction and two new stories, "Mercury" and "Salammbô Redux", and omitting the story "Angels You Can See Through".  All three editions include artwork by Canadian illustrator Richard A. Kirk, as well as an introduction by anthologist/novelist Douglas E. Winter and an afterword by novelist Peter Straub. The Tales of the Late Ivan Petrovich Belkin (Russian: Повести покойного Ивана Петровича Белкина) (1831) is a series of five short stories and a fictional editorial introduction by Russian author Aleksandr Pushkin.  The collection is opened with the editorial, in which Pushkin pretends to be the verbose publisher of Belkin's tales.  The tales themselves are not related to one another, except that they are all said in the introduction to be stories told by various people to a recently deceased landowner, Ivan Petrovich Belkin.  The introduction continues to say that Belkin was an interesting and mysterious man, even to the point that the woman he left his estate to had never met him.  It is also mentioned that Belkin's favorite pastime was to collect and hear stories, several of which are to be presented to the reader. Nick Tosches ( ; born October 17 or 23, 1949) is an American journalist, novelist, biographer, and poet.  His 1982 biography of Jerry Lee Lewis, "Hellfire", was praised by "Rolling Stone" magazine as "the best rock and roll biography ever written." Sweets and Other Stories is the 2009 debut novel by soul singer Andre Williams.  It features an introduction by author Nick Tosches and an editor's note by Miriam Linna of Kicks Books. The Man Booker International Prize is an international hosted in the United Kingdom.  The introduction of the International Prize to complement the Man Booker Prize was announced in June 2004.  Sponsored by the Man Group, from 2005 until 2015 the award was given every two years to a living author of any nationality for a body of work published in English or generally available in English translation.  It rewarded one author's "continued creativity, development and overall contribution to fiction on the world stage", and was a recognition of the writer's body of work rather than any one title.  The judges for the year compiled their own lists of authors, and submissions were not invited. Amateur in Violence is a collection of mystery stories by the prominent British thriller writer Michael Gilbert, published in the United States in 1973 by Davis Publications, a publishing house for magazines, but not in England.  Gilbert, who was appointed CBE in 1980, was a founder-member of the British Crime Writers' Association.  The Mystery Writers of America named him a Grand Master in 1988 and in 1990 he was presented Bouchercon's Lifetime Achievement Award.  The book is edited, and has an introduction, by Ellery Queen, the founder and long-term editor of Ellery Queen's Mystery Magazine.  It contains 10 stories and a short novel that had been previously uncollected in the United States.  Some of them feature characters who have figured in other novels and short stories by Gilbert.  Three stories feature Inspector Hazlerigg and four Inspector Petrella.  The short novel, "Stay of Execution", had previously given its name to the title of a collection published in England in 1971. "On the Quai at Smyrna" is a short story written by Ernest Hemingway, first published in the 1930 Scribner's edition of the "In Our Time" collection of short stories, then titled "Introduction by the author".  Accompanying it was an introduction by Edmund Wilson.  Considered little more than a vignette, the piece was renamed "On the Quai at Smyrna" in the 1938 publication of "The Fifth Column and the First Forty-Nine Stories".  When "In Our Time" was reissued in 1955, it led with "On the Quai at Smyrna", replacing "Indian Camp" as the first story of the collection. Venus on the Half-Shell and Others (ISBN  ) is a collection mostly of science fiction author Philip José Farmer's pseudonymous fictional-author literary works, edited by Christopher Paul Carey and published in 2008.  Farmer describes a fictional-author story as "a tale supposedly written by an author who is a character in fiction."  Carey, who had access to Farmer's correspondence while editing the book, reveals in his introduction that in the early to mid-1970s Farmer planned to edit an anthology of fictional-author stories by other writers.  Farmer solicited fictional-author stories from authors such as Arthur Jean Cox, Philip K. Dick, Leslie Fiedler, Ron Goulart, Howard Waldrop, and Gene Wolfe, urging them to submit their stories to venues such as "The Magazine of Fantasy and Science Fiction".  Only Cox, Waldrop, and Wolfe completed their stories and had them published, although Philip K. Dick's never realized fictional-author story "A Man for No Countries" as by Hawthorne Abendsen is said to have led Dick to write his posthumous novel "Radio Free Albemuth".  In the end, Farmer's fictional-author anthology never materialized.
