My Best Science Fiction Story is an anthology of science fiction short stories edited by Leo Margulies and Oscar J. Friend. It was first published in hardcover by Merlin Press in November 1949, and reprinted in August 1950. An abridged paperback edition including twelve of its twenty-five stories was published by Pocket Books in July 1954 and reprinted in November 1955.The book collects twenty-five self-selected short stories and novelettes by as many science fiction authors, together with a general introduction by the editors and brief introductory essays prefacing each story by its author explaining the selection, each titled "Why I Selected '[Title of Story].' The selections are generally presented in alphabetical order by author (though the Heinlein piece is out of order). The stories were previously published from 1930-1949 in various science fiction and other magazines. Source: Wikipedia (en)
