Lord Byron 
Works Of Lord Byron, Letters and Journals, Vol 2 

Excerpt: "The material contained in these two volumes consists partly of letters now for the first time printed; partly of letters already published by Moore, Dallas, and Leigh Hunt, or in such books as Galt’s Life of Lord Byron, and the Memoirs of Francis Hodgson. Speaking generally, it may be said that the text of the new matter, with the few exceptions noted below, has been prepared from the original letters, and that it has proved impossible to authenticate the text of most of the old material by any such process."
