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.
Driftglass/Starshards is a 1993 collection of short stories by Samuel R. Delany.
 The collection contains the entire contents of Delany's 1971 collection, "Driftglass", stories from "Distant Stars" (1981) and others that had not previously been collected.
 Many of the stories originally appeared in the magazines "Worlds of Tomorrow", "The Magazine of Fantasy & Science Fiction", "If" and "New Worlds" or the anthologies "Quark/3", "Dangerous Visions" and "Alchemy & Academe".
"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."
Samuel Ray Delany Jr. ( ; born April 1, 1942), Chip Delany to his friends, is an American author, professor and literary critic.

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.
Empire Star is a 1966 science fiction novella by Samuel R. Delany.

 It was finally bundled with "Babel-17" in a 2001 reprint.
