Do not reject an otherwise good copy of a book because the case is loose or the back-stitching perished. Such deterioration is easily and painlessly repaired.

In the case of books illustrated with etchings or steel engravings, compare the date often to be found on the plates with that on the title-page. These dates should tally, or, if they do not, thought or examination of prefatory matter should show the reason why.

Several cases exist of books reissued more than once, but without printed indication of reissue, in a style identical with that of the first edition. In such cases the plates, more often than not, bear their silent witness, and the careful buyer, momentarily uncertain of his dates, is saved the purchase of a book he does not want.

(viii) The volumes listed which I have not myself seen and examined are asterisked and thus expressly noted as catalogued without personal investigation. As may be imagined, some of the obscurer works of the authors dealt with are extremely rare, and all my seeking has failed to discover some of them. In every other case personal handling has preceded analysis, even although collation may already have existed in published form.

(ix) In conclusion I would appeal to any reader of my book who can emend, develop, or dispute the statements therein contained to send me forthwith his criticisms and suggestions. To work of this kind can be no finality. Freak copies, copies containing catalogues of earlier date, copies in earlier varieties of binding—of such things is the sport of bibliography composed. No individual can be sure that one particular issue of any book is the earliest; comparative certainty comes only from cooperation. Wherever possible I have compared several copies of the same book, but this was by no means everywhere. Consequently to look forward to revision and yet more revision is, in the circumstances, a matter for hope rather than one for shame.

ACKNOWLEDGMENTS

Perhaps the most pleasant element in the compiling of this book has been the generosity and enthusiasm with which persons able to help have responded to inquiries.

Among those who have contributed of their private knowledge facts that but for them I could never have discovered, Mr. Richard Bentley must have first place. Unique as an authority on Victorian publishing, Mr. Bentley not only replied promptly and in detail to my importunate inquiries, but made suggestions and gave information—often at considerable personal trouble—which have greatly extended the scope and utility of my book.

Other publishers and editors were no less ready to give me access to such records of the past as were still in their keeping. To Mr. Arthur Waugh (of Messrs. Chapman and Hall), to Mr. Kelk and to Mr. Barnard (of Messrs. Longmans, Green), to Mr. Spalding (of Messrs. Chatto and Windus), to Mr. Herbert Virtue (of Messrs. Virtue and Co.), to Mr. Farquharson and to Mr. Leonard Huxley (of Messrs. John Murray), to Mr. Marston (of the “Publishers' Circular”), I tender my best thanks.

Gratitude must next be expressed to booksellers and owners of books whose contribution differed in kind but not in degree from that of the foregoing. Mr. Walter Spencer put his unrivalled stock of Victorian first editions wholly at my disposal, thus enabling me to examine many rare items not elsewhere discoverable. He also lent me a series of autograph letters from which certain details were obtainable. To Messrs. Bain and Messrs. Maggs I owe opportunities of seeing books necessary to my list. Mr. Hugh Walpole gave me access to his private collection, and Mr. Cecil Davis, Mr. J. A. Green, and Mr. Clement Shorter helped to a clearer understanding of the bibliography of Captain Marryat and of Mrs. Gaskell.
