In Greek mythology, Ariadne gave Theseus a ball of red thread to guide him through the labyrinth, and the offers a path through and a way to explore the ins and outs and twists and turns of the celebrated NYRB Classics series, now twenty years old. The collection brings together twenty-five pieces drawn from the more than five hundred books that have come out as NYRB Classics over the last twenty years. Stories, essays, interviews, poems, along with chapters from novels and memoirs and other longer narratives have been selected by Edwin Frank, the series editor, to chart a distinctive, entertaining, and thought-provoking course across the expansive and varied terrain of the Classics series.
