Aye, and Gomorrah
"Aye, and Gomorrah..." is a science fiction short story by American writer Samuel R. Delany.
 It is the first short story Delany sold, and won the 1967 Nebula Award for best short story.
 Before it appeared in "Driftglass" and "Aye, and Gomorrah, and other stories", it first appeared as the final story in Harlan Ellison's seminal 1967 anthology, "Dangerous Visions".
 It was controversial because of its disturbing sexual subject matter, and has been called "one of the best stories by a gay man published in the 1960s." Empire Star
Empire Star is a 1966 science fiction novella by Samuel R. Delany.
 It is often published together with another book, most frequently (three times) with "The Ballad of Beta-2".
 Delany hoped to have it first published as part of an Ace Double with "Babel-17", but instead it was published with "Tree Lord of Imeten" by Tom Purdom.
 It was finally bundled with "Babel-17" in a 2001 reprint. The Einstein Intersection
The Einstein Intersection is a 1967 science fiction novel by Samuel R. Delany.
 It won the Nebula Award for Best Novel in 1967 and was nominated for the Hugo Award for Best Novel in 1968.
 Delany's intended title for the book was "A Fabulous, Formless Darkness". The Mad Man
The Mad Man is a sexually drenched literary novel by Samuel R. Delany, first published in 1994 by Richard Kasak.
 In a disclaimer that appears at the beginning of the book, Delany describes it as a "pornotopic fantasy".
 It was originally published in 1994, republished and slightly revised in 1996, and republished again with significant changes in 2002 and again in an e-book version with further corrections in 2015.
 Delany considers the 2015 version the definitive edition. The Complete Nebula Award-Winning Fiction
The Complete Nebula Award-Winning Fiction is a 1986 collection of short stories and novellas by Samuel R. Delany.
 The collection includes those works by Delany that have won the Nebula Award. The Motion of Light in Water
The Motion of Light in Water: Sex and Science Fiction Writing in the East Village is an autobiography by science fiction author Samuel R. Delany in which he recounts his experiences as growing up a gay African American, as well as some of his time in an interracial and open marriage with Marilyn Hacker.
 It describes encounters with Albert Einstein, Bob Dylan, and Stokely Carmichael, a dinner with W. H. Auden, and a phone call to James Baldwin.
 Hazel Carby called it one of two contemporary autobiographies that are "absolutely central to any consideration of black manhood" (the other being that of Miles Davis).
 Among many cultural events of the decade that he witnessed, Delany recounts his attendance at the first New York City performance of artist Allan Kaprow's "18 Happenings in 6 Parts", the 1959 performance piece that, for many, marks the end of modernism and the beginning of postmodernism.
 In section 17.4 of the University of Minnesota Press edition, he describes the event and its venue, and speculates on its artistic significance.
 The introduction puts an emphasis on the idea of the unreliable narrator; Delany's accounts often contrast his life as it "felt" to ways in which it actually occurred.
 In the chapter, The Future Is in the Present of the book "Cruising Utopia" by José Esteban Munoz, Delany's The Motion of Light in the Water serves to explain how the future, as a formed of utopia, can be "glimpsed" in the present through what Delany employed as "the massed bodies" of sexual dissidence. Stars in My Pocket Like Grains of Sand
Stars in My Pocket Like Grains of Sand (1984) is a science fiction novel by Samuel R. Delany.
 It was part of a planned duology ("diptych", in Delany's description) whose second half, "The Splendor and Misery of Bodies, of Cities", remains unfinished. Aye, and Gomorrah, and other stories
Aye, and Gomorrah, and other stories is a collection of stories by American writer Samuel R. Delany, published by Vintage Books in 2003.
 It is a thematically arranged collection, in the style of James Joyce’s "Dubliners" (1914), Sherwood Anderson’s "Winesburg, Ohio" (1919), and Willa Cather’s "Youth and the Bright Medusa" (1920).
 The book is closely based on an earlier collection, "Driftglass", which first appeared in 1971.
 The dedication to the two books is similar: one is simply an updated version of the other, dedicating the book to Delany’s immediate family: his maternal grandmother, mother, sister, and father.
 Both carry identical epigraphs.
 The ten tales contained in "Driftglass" are all contained in "Aye, and Gomorrah", along with five other stories ("Omegahelm", "Among the Blobs", "Tapestry", "Prismatica", "Ruins").
 The stories consist of ten science fiction tales, in the order the writer wrote them, followed by five fantasies, also in chronological order.
