Beloved author of The Canterbury Tales and foundation of the English literary tradition, Geoffrey Chaucer has been popular with readers, writers and scholars for over 600 years. More than 4600 books, essays, poems, stories, recordings and websites pertaining to Chaucer were published between 1997 and 2010, and this bibliography identifies each of them separately, providing full publication information and a descriptive summary of contents, thoroughly cross-listed and indexed. The bibliography also cites reviews for individual books, and offers several useful discovery aids to enable users to locate individual items of interest, whether it be a study of the Wife of Bath's love life, a video about Chaucer's language, advice on how to teach a particular poem by Chaucer, or a murder mystery that features Chaucer as detective. Designed for the international audience of Chaucer students and scholars, the bibliography identifies not only traditional academic studies but pedagogical and popular materials as well. It covers digital and print matter, including a comprehensive range of materials that pertain to Chaucer's life, works and ongoing influence: books, essays, poems, stories, translations and modernizations, websites, recordings and films. A unique feature, not found in previous Chaucer bibliographies, is the classification "Chaucer in fiction". The book extends into the twenty-first century the unbroken legacy of cumulative Chaucer bibliographies, and it is a fundamental reference work for those interested in early English literature, the history of the English language, medieval studies, manuscript studies and studies of gender, identity and nation. Its taxonomy of classifications is highly refined and its author and subject indexes are comprehensive. It contains nearly 200 items published before 1997 missed in previous Chaucer bibliographies.
