Book excerpt: Joyce Carol Oates has performed a full review of her acclaimed 1992 anthology, The Oxford Book of American Short Stories, and in this second edition embraces those authors who have come to define turn-of-the-century American literature. Jhumpa Lahiri, Junot Diaz, Richard Ford, and David Foster Wallace are just a few of the authors whose stories are now represented. Each story is accompanied by a brief introduction, and there is also a fascinating introductory essay by Joyce Carol Oates that explains why these stories form the foundation of the American literary canon, and the trends and innovations that have taken place in the last twenty years.
