In an attempt of this scope, I have necessarily had to repeat matters of common knowledge and to say again things that others have said well and sufficiently already. But working from materials hitherto in part untouched, and taking notice of such new lights as have appeared while my task was in progress, I have drawn from them some conclusions, both biographical and critical, which I believe to be my own and which I hope may stand. I have not shrunk from quoting in full poems and portions of poems which everybody knows, in cases where I wanted the reader to have their text not merely in memory but actually before him, for re-studying with a fresh comment or in some new connexion. I have also quoted very largely from the poet's letters, even now not nearly as much read as things so full of genius should be, both in order that some of his story may be told in his own words and for the sake of that part of his mind--a great and most interesting part--which is expressed in them but has not found its way into his poems. It must be added that when I found things in my former small book which I did not see my way to better and which seemed to fit into the expanded scale of this one, I have not hesitated sometimes to incorporate them--to the amount perhaps of forty or fifty pages in all. I wish I could hope that my work will be found such as to justify the amount and variety of friendly help I have had in its preparation. Thanks for such help are due in more quarters than I can well call to mind. First and foremost, to Lord Crewe for letting me have free and constant access to his unrivalled collection of original documents connected with the subject, both those inherited from his father (referred to in the notes as 'Houghton MSS.') and those acquired in recent years by himself (referred to as 'Crewe MSS.'). Speaking generally, it may be assumed that new matter for which no authority is quoted is taken from these sources. To Miss Henrietta Woodhouse of Weston Lea, Albury, I am indebted for valuable documentary and other information concerning her uncle Richard Woodhouse. Next in importance among collections of Keats documents to that of Lord Crewe is that of Mr J. P. Morgan in New York, the chief contents of which have by his leave been transcribed for me with the kindliest diligence by his librarian Miss Greene. For other illustrative documents existing in America, I believe of value, I should like to be able to thank their owners, Mr Day and Mr Louis Holman of Boston: but these gentlemen made a condition of their help the issue of a limited edition _de luxe_ of the book specially illustrated from their material, a condition the publishers judged it impossible to carry out, at any rate in war-time.
