This authoritative edition was originally published in the acclaimed Oxford Authors series under the general editorship of Frank Kermode. It brings together a unique combination of Coleridge´s poetry and prose - all the major poems, complemented by important criticism, letters, and marginalia - to give the essence of his work and thinking. Samuel Taylor Coleridge, poet, critic, and radical thinker, exerted an enormous influence over contemporaries as different as Wordsworth, Southey and Lamb. He was also a dedicated reformer, and set out to use his reputation as a public speaker and literary philosopher to change the course of English thought. This collection represents the best of Coleridge´s poetry from every period of his life, particularly his prolific early years, which produced The Rime of the Ancient Mariner, Christabel, and Kubla Khan. The central section of the book is devoted to his most significant critical work, Biographia Literaria, and reproduces it in full. It provides a vital background for both the poetry section which precedes it and for the shorter prose works which follow. There is also a generous sample of his letters, notebooks, and marginalia, some recently discovered, which show a different, more spontaneous side to his fascinating and complex personality.
