In correspondence, Willa Cather confessed to planting some of her allusions deep. This reader’s companion contains thousands of lively and informative entries on persons, places, and events, fictional and real, and on quotations, works of art, and other items to reveal meanings or provide background for understanding Cather’s fictional world. At the same time, it offers insights into her real world and time, her interests, and her astonishingly broad frame of reference. A lifetime project of encyclopedist John March, the once unwieldy manuscript and notes have been verified, clarified, amplified, and organized by literary scholar Marilyn Arnold, with the assistance of Debra Lynn Thornton. The goal was to develop a work that would be useful to the reader while preserving March’s authorial presence has resulted in a dictionary that will both enlighten and delight.
