It shared the 1974 National Book Award for Fiction with Thomas Pynchon.  The twenty-four (24) stories in this collection were translated from Yiddish (Singer's language of choice for writing) by Singer, Laurie Colwin, and others.

While Mortals Sleep (short story collection): While Mortals Sleep is a collection of sixteen previously unpublished short stories by Kurt Vonnegut, released on January 25, 2011.  It is the third posthumously published Kurt Vonnegut book, the first being "Armageddon in Retrospect", the second being "Look at the Birdie".  The book begins with a foreword by Dave Eggers.  Illustrations by Vonnegut himself appear throughout.

Kurt Vonnegut: Kurt Vonnegut Jr. ( ; November 11, 1922April 11, 2007) was an American writer.  In a career spanning over 50 years, Vonnegut published 14 novels, three short story collections, five plays, and five works of non-fiction.  He is most famous for his darkly satirical, best-selling novel "Slaughterhouse-Five" (1969).

Kurt Vonnegut Sr.: Kurt Vonnegut Sr. (November 24, 1884 – October 1, 1957) was an American architect and architectural lecturer active in early- to mid-twentieth-century Indianapolis, Indiana.  A member of the American Institute of Architects, he was partner in the firms of Vonnegut & Bohn, Vonnegut, Bohn & Mueller, and Vonnegut, Wright, and Yeager.  He designed several churches, banks, and became the inhouse architect for Indiana Bell and Hooks Drug stores (prior to World War II), practicing extensively in the Art Deco style.  He was the father of chemist Bernard Vonnegut and author Kurt Vonnegut Jr.

A Man Without a Country: A Man Without a Country (subtitle: "A Memoir Of Life In George W Bush's America") is an essay collection published in 2005 by the author Kurt Vonnegut.  The extremely short essays that make up this book deal with topics ranging from the importance of humor, to problems with modern technology, to Vonnegut's opinions on the differences between men and women.  Most prevalent in the text, however, are those essays that elucidate Vonnegut's opinions on politics, and the issues in modern American society, often from a decidedly humanistic perspective.  In January 2007, Vonnegut indicated that he intended this to be his final work, a statement that proved to be correct with his death in April 2007.  Later published works of Vonnegut's were all published posthumously, and consisted almost entirely of previously unpublished material from early in his career.

Venus on the Half-Shell: Venus on the Half-Shell is a science fiction novel by American writer Philip José Farmer, writing pseudonymously as "Kilgore Trout", a fictional recurring character in many of the novels of Kurt Vonnegut.  This book first appeared as a lengthy fictitious "excerpt"—written by Vonnegut, but attributed to Trout—in Vonnegut's "God Bless You, Mr. Rosewater" (1965).  With Vonnegut's permission, Farmer expanded the fragment into an entire standalone novel (including, as an in-joke, a scene that incorporates all of Vonnegut's original text).  Farmer's story was first published in two parts beginning in the December 1974 issue of "The Magazine of Fantasy and Science Fiction".  The plot, in which Earth is destroyed by cosmic bureaucrats doing routine maintenance and the sole human survivor goes on a quest to find the "Definitive Answer to the Ultimate Question," was paid homage by the later "Hitchhiker's Guide to the Galaxy" series.

Look at the Birdie: Look at the Birdie is a collection of fourteen previously unpublished short stories by Kurt Vonnegut, released on October 20, 2009.  It is the second posthumously published Kurt Vonnegut book, the first being "Armageddon in Retrospect".
