In the case of early-printed books and works of great rarity, never, upon any account, tamper with your copy or seek to improve it in any way. Not only, as I have said, is it quite impossible to impart a contemporary appearance to a fifteenth-century book however famous and skilful the binder, but age leaves its mark upon the constitutions of books as surely as it does upon mankind. No volume of that age will stand the handling of a casual reader, still less the pulling, patting, and pressing that re-sewing and re-covering necessitate, however gently such processes be carried out.

There is a terrible story (I hope it is untrue) told of a certain peer who decided to send to the auction-room the six or seven Caxtons which had descended to him with a noble library from his ancestors. As, however, the volumes were bound in fifteenth-century sheepskin (probably in Caxton's house) he thought that their appearance would be rendered rather more attractive if they were rebound first of all. So he sent them forthwith to the local binder; and on their return, now gorgeously clothed in 'calf gilt extra' (à la school prize), he despatched them to the London sale-room. The result may be imagined. His foolishness must have robbed him of a sum running well into four figures!

There is another point also to be considered, and that is the pedigree of a volume. The solitary impression of a binder's tool upon a fragment of binding may identify a volume and its previous owners. Some years ago the writer purchased an ancient folio without title-page and colophon, bound in tattered fragments of ancient calf covering stout oak boards. There was, apparently, nothing to indicate when, where, or by whom the volume was printed or bound, or whence it came. But from a certain peculiarity in the type (which he noticed when studying the early printers of Nürnberg) he now knows the name of the printer and the town in which he plied his trade; while from a certain woodcut which that printer used also in two other dated works only, both printed the same year, he discovered when the volume in all probability was printed.

A scrutiny of the remains of the binding revealed the blind impressions of four different stamps. As these occur frequently in conjunction upon the bindings executed by the monks at a certain monastery in Germany in the sixteenth century, there is little difficulty in assigning a provenance to the volume. Furthermore the initial H in a heart-shaped impression identifies the binder as a monk whose initials H.G. (on two heart-shaped tools) are of frequent occurrence on contemporary volumes at that time in the possession of the monastery.

Needless to say, it has not been rebound. The tattered pieces of skin have been carefully pasted down, and a case—lettered on the back—now contains the book upon his shelf.[45]

In the case, however, of more recent books bound in tattered or perished calf, books of which one may obtain duplicates at any time, except they be works of extreme value there is no reason why they should not be re-bound. Even here, however, the collector must tread warily; for should he send his copy of Tim Bobbin's Lancashire dialogue of Tummus and Meary to the binders with brief instruction that it is to be bound in full morocco, it may be returned to him in all the splendour of a sixteenth-century Florentine binding.

With regard to books published in cardboard covers with paper backs and paper labels, what is to be done with these when the backs are dirty or torn off, the labels of some volumes missing? Must they be re-bound in leather or cloth? Not necessarily, and I for my part maintain that the delightful ease which one experiences in handling them when reading the early editions of Byron, Scott, or Irving, and those writers who flourished in the first few decades of the nineteenth century when books were commonly issued in this form, is sufficient excuse for retaining them in their original shape. Such volumes may easily be made presentable at the cost of a little time and trouble, as I shall presently show.

An appearance of antiquity is never a desideratum to the honest book-collector. I say 'honest' advisedly, for there have been—and doubtless are—persons so misguided as to stoop to the fabrication of certain small and excessively valuable books. To such, an appearance of age is no doubt indispensable in their wares. But these are torments which afflict the wealthy only; and for this I at least am sincerely thankful.

There is no doubt, however, that in the collection of many things antiquity in appearance is desirable: witness the modern fabrication of 'antique' furniture and pottery. Our book-hunter was once acquainted with a certain country gentleman, a learned man and most excellent companion, whose passion for rare things once got the better of his judgment. It was not books that he collected, but butterflies; and he was inordinately proud of a rather seedy-looking 'Large Copper' which his cabinet contained. For the benefit of his admiring entomological friends he would recite how his grandfather had caught it with his hat when on a holiday in the Fens. It grew to be quite an exciting tale. One day, however, in the course of a country ramble they fell to discussing the romancer, or man who resorts to fiction that his adventures may be the more interesting. And as (for the sake of argument) the man of books affected to praise him, remarking that any soulless fool can tell the bald truth whereas it requires an artistic temperament to adorn a tale with realistic embellishment (!), his friend turned to him eagerly. Being encouraged, he confessed that his Large Copper was not all that it appeared to be. In short, the bookman discovered that he had secured it himself while on a summer tour in Switzerland, and with the aid of a camel's-hair brush had succeeded in reducing it to a venerable state.

'Of course,' the entomologist hastened to explain, 'no one could possibly tell that it was not my grandfather's. He had a very fine collection, and probably there was more than one Large Copper in it, though there was only the one in the cabinet that came to me. I shall never forget my feelings when it happened. I had taken it out of the drawer to show to a friend, when we both saw, outside the window, what we thought was an Antiopa. We rushed out, and when we came back we found that the cat. . . . Dear me; I was quite overcome. . . . But that summer I caught the one you have seen in Switzerland; and as my dear friend was no more and nobody else knew of the catastrophe, I thought there would be no harm in merely restoring a specimen to my grandfather's collection.'
