Anthologies seldom make history, but Dangerous Visions is a grand exception. Harlan Ellison's 1967 collection of science fiction stories set a standard, as more than a half dozen of its stories won major awards -- not surpising with a contributors list that reads like a who's who of 20th-century SF: Samuel D. Delany, Philip K. Dick, Ben Bova, Roger Zelazny, Philip José Farmer, Fritz Leiber, Larry Niven, and Robert Silverberg. Unavailable for 15 years, this huge anthology now returns to print with a new introduction and annotations by Ellison.
