25) Science Fiction Hall of Fame: The Greatest Science Fiction Stories of All Time, edited by Robert Silverberg
This is one of those classic collections, assembling the top sf stories published before 1965 as voted for by the membership of SFWA in the late 1960s. (I wonder how different the results would be, if a similar poll were taken now?) Most of these stories were very familiar to me, but it filled in a couple of gaps - I don't think I had read either Theodore Sturgeon's "Microcosmic God" or Alfred Bester's "Fondly Fahrenheit" before. Anyway it's good to have such a selection of classics within a single set of covers.
