    Selected by a vote of the membership of the Science Fiction Writers of America (SFWA), these 26 reprints represent the best, most important, and most influential stories and authors in the field. The contributors are a Who's Who of classic SF, with every Golden Age giant included: Isaac Asimov, Ray Bradbury, Arthur C. Clarke, John W. Campbell, Robert A. Heinlein, Fritz Leiber, Cordwainer Smith, Theodore Sturgeon, and Roger Zelazny. Other contributors are less well known outside the core SF readership. Three of the contributors are famous for one story--but what stories!--Tom Godwin's pivotal hard-SF tale, "The Cold Equations"; Jerome Bixby's "It's a Good Life" (made only more infamous by the chilling Twilight Zone adaptation); and Daniel Keyes's "Flowers for Algernon" (brought to mainstream fame by the movie adaptation, Charly). The collection has some minor but frustrating flaws. There are no contributor biographies, which is bad enough when the author is a giant; but it's especially sad for contributors who have become unjustly obscure. Each story's original publication date is in small print at the bottom of the first page. And neither this fine print nor the copyright page identifies the magazines in which the stories first appeared. Prefaced by editor Robert Silverberg's introduction, which describes SFWA and details the selection process, The Science Fiction Hall of Fame: Volume One, 1929-1964 is a wonderful book for the budding SF fan. Experienced SF readers should compare the table of contents to their library before making a purchase decision. Fans who contemplate giving this book to non-SF readers should bear in mind that, while several of the collected stories can measure up to classic mainstream literary stories, the less literarily-acceptable stories are weighted toward the front of the collection; adult mainstream-literature fans may not get very far into The Science Fiction Hall of Fame: Volume One, 1929-1964. --Cynthia Ward· Introduction · Robert Silverberg · in · A Martian Odyssey [Tweel] · Stanley G.

    Now the abscess was about to burst. Captain Harris had left the controls on autopilot and was talking to the front row of passengers as the first tremor shook the boat. For a fraction of a second he wondered if a fan blade had hit some submerged obstacle; then, quite literally, the bottom fell out of his world.It fell slowly, as all things must upon the Moon. The sea was alive and moving . . . Every stage of that nightmare transformation was pitilessly illuminated by the earth light, until the crater was so deep that its firewall was completely lost in shadow, and it seemed as if Selene were racing into a curving crescent of utter blackness – an arc of annihilation.In darkness and in silence, they were sinking into the Moon. . . .
