The standard edition of Byron’s _Poetical Works_ is that by Ernest Hartley Coleridge in seven volumes (London, 1904), which contains an exhaustive bibliography of the successive editions and translations of different poems. The most complete collection of the _Letters and Journals_ is that by Rowland E. Prothero in six volumes (London, 1902). Any study of Byron must be largely based on these comprehensive and scholarly works. A fairly detailed list of critical articles on Byron was compiled by Roden Noel in his _Life of Lord Byron_; this, however, needs to be supplemented and revised in the light of recent investigation. The following list includes only the more important sources of information for this treatise.
