With only two stories each from The Atlantic and The New Yorker, the rest of the choices in this year's annual appeared originally in little magazines and reviews. Few will quarrel with the generally high literary level of the collection which includes Katherine Anne Porter's Holiday. Thomas Pynchon's Under the Rose. Tom Cole's Familiar Usage in Leningrad. O'Hara's The Girl from California and other outstanding contributions. Young readers eager to keep up with modern trends in short story writing will find provocative material here.
