This is the next-to-last annual anthology that Wollheim edited with his picks of the best short science fiction from the previous year. From the mid-1960's on, he and Terry Carr were the consistent experts to look to for the trends and twists and turns the field was taking. They edited the first volumes together when both were at Ace Books, then began producing separate volumes, Carr as a freelance from Ballantine (later Del Rey) Books, and Wollheim, of course, from the company that he founded and that bears his name to this day. (Carr died in 1987, and Wollheim in 1990.) This penultimate volume is a very good one, and has a very touching introduction by Isaac Asimov. The authors include David Brin, Steven Gould, John Shirley, Ian Watson, Kristine Kathryn Rusch, Tanith Lee, Frederik Pohl, B.W. Clough, and Jack L. Chalker. My favorite stories are Ripples in the Dirac Sea by Geoffrey A. Landis and Schrodinger's Kitten by George Alec Effinger.
