The Cambridge Chaucer companion

"Contains a series of essays by internationally known Chaucer experts, designed to provide a challenging introduction to the poet. The collection is divided between pieces which concentrate squarely on one or more of Chaucer's major poems, identifying themes, styles, moods and tones, and pieces of wider scope which give more general information about Chaucer's literary sources and historical background, or study his experiments with style and structure over a range of poems, or set his works in the context of medieval genres and literary traditions."--Amazon description.
