This handbook takes stock of current developments in the study of a major Romantic poet and prose-writer, and seeks to advance Shelley studies beyond the current scholarship. It consists of forty-two chapters written by a prestigious international cast of established and emerging scholar-critics, and offers the most wide-ranging single-volume body of writings on Shelley. The volume builds on the textual revolution in Shelley studies, which has transformed understanding of the poet, as critics are able to focus on what Shelley actually wrote. This handbook is divided into five thematic sections: Biography and Relationships; Prose; Poetry; Cultures, Traditions, Influences; and Afterlives.
