Biographia Literaria.

Biographia Literaria, or in full Biographia Literaria; or Biographical Sketches of My Literary Life and Opinions, is an autobiography in discourse by Samuel Taylor Coleridge, which he published in 1817, in two volume of twenty-three chapters. The work is long and seemingly loosely structured, and although there are autobiographical elements, it is not a straightforward or linear autobiography. Instead, it is meditative. The work was originally intended as a mere preface to a collected volume of his poems, explaining and justifying his own style and practice in poetry. The work grew to a literary autobiography, including, together with many facts concerning his education and studies and his early literary adventures, an extended criticism of William Wordsworth's theory of poetry as given in the preface to the Lyrical Ballads (a work on which Coleridge collaborated), and a statement of Coleridge's philosophical views.
