S. T. Coleridge, and a collation of the text of the 'Introduction to the Tale of the Dark Ladié', as published in the Morning Post, Dec. 21, 1799, with two MSS. preserved in the British Museum, are included in Appendix No. I.

The text of the 'Allegoric Vision' has been collated with the original MS. and with the texts of 1817 and 1829.

A section has been devoted to 'Metrical Experiments'; eleven out of thirteen are now published for the first time. A few critical notes by Professor Saintsbury are, with his kind permission, appended to the text.

Numerous poems and fragments of poems first saw the light in 1893; and now again, in 1912, a second batch of newly-discovered, forgotten, or purposely omitted MSS. has been collected for publication. It may reasonably be asked if the tale is told, or if any MSS. have been retained for publication at a future date. I cannot answer for fresh discoveries of poems already published in newspapers and periodicals, or of MSS. in private collections, but I can vouch for a final issue of all poems and fragments of poems included in the collection of Notebooks and unassorted MSS. which belonged to Coleridge at his death and were bequeathed by him to his literary executor, Joseph Henry Green. Nothing remains which if published in days to come could leave the present issue incomplete.

A bibliography of the successive editions of poems and dramas published by Coleridge himself and of the principal collected and selected editions which have been published since 1834 follows the Appendices to this volume. The actual record is long and intricate, but the history of the gradual accretions may be summed up in a few sentences. 'The Fall of Robespierre' was published in 1795. A first edition, entitled 'Poems on Various Subjects', was published in 1796. Second and third editions, with additions and subtractions, followed in 1797 and 1803. Two poems, 'The Rime of the Ancyent Marinere' and 'The Nightingale, a Conversation Poem', and two extracts from an unpublished drama ('Osorio') were included in the Lyrical Ballads of 1798. A quarto pamphlet containing three poems, 'Fears in Solitude,' 'France: An Ode,' 'Frost at Midnight,' was issued in the same year. 'Love' was first published in the second edition of the Lyrical Ballads, 1800. 'The Three Graves,' 'A Hymn before Sunrise, &c.,' and 'Idoloclastes Satyrane', were included in the Friend (Sept.-Nov., 1809). 'Christabel,' 'Kubla Khan,' and 'The Pains of Sleep' were published by themselves in 1816. Sibylline Leaves, which appeared in 1817 and was described as 'A Collection of Poems', included the contents of the editions of 1797 and 1803, the poems published in the Lyrical Ballads of 1798, 1800, and the quarto pamphlet of 1798, but excluded the contents of the first edition (except the 'Eolian Harp'), 'Christabel', 'Kubla Khan', and 'The Pains of Sleep'. The first collected edition of the Poetical Works (which included a selection of the poems published in the three first editions, a reissue of Sibylline Leaves, the 'Wanderings of Cain', a few poems recently contributed to periodicals, and the following dramas—the translation of Schiller's 'Piccolomini', published in 1800, 'Remorse'—a revised version of 'Osorio'—published in 1813, and 'Zapolya', published in 1817) was issued in three volumes in 1828. A second collected edition in three volumes, a reissue of 1828, with an amended text and the addition of 'The Improvisatore' and 'The Garden of Boccaccio', followed in 1829.

Finally, in 1834, there was a reissue in three volumes of the contents of 1829 with numerous additional poems then published or collected for the first time. The first volume contained twenty-six juvenilia printed from letters and MS. copybooks which had been preserved by the poet's family, and the second volume some forty 'Miscellaneous Poems', extracted from the Notebooks or reprinted from newspapers.
