This new edition of the Biographia supersedes all previous editions. Crucially, it takes into consideration 3 decades of research and scholarship on Coleridge and includes all Coleridge's references and allusions. In tracing all unattributed references, Adam Roberts has in some cases opened up whole new avenues of interpretation for the text, materially altering or changing the way we read this classic work. This new scholarly edition for a 21st-century readership includes a detailed Critical Introduction, a Textual Introduction, the text of the Biographia Literaria, including Coleridge's notes and editorial footnotes; Endnotes; and a Bibliography. It is likely to stand as the definitive textual edition for many years to come.
