The following chapters contain suggestions partly gathered from the experience of others and partly evolved for myself in caring for my own books. Although many books about books have already been written, there is still, I think, a place for this one. I have designed it especially for the bibliophile who enjoys fussing over his books and who receives, in seeing them in good condition and repair through his own efforts, an echo of the pleasure he receives from reading them. In translating from Bonnardot, I have taken the liberty of abridging or paraphrasing, at times, the chapters which I have included here, not only to confine the subjects a little more closely but also to present his essential suggestions as concisely as possible. His book, copies of which are very scarce, was first issued in an edition of four hundred copies in 1846 and re-issued, with revisions, in 1858. It has not since been reprinted nor, so far as I have been able to learn, has it been translated into English, either wholly or in part. To consider first a few simple processes of ordinary restoration, let us assume that a rare book in its original cloth or boards, in a more or less damaged condition but not to the point of necessitating rebinding, has just been received. The first operation required is to carefully clean off the binding with a soft cloth, wipe off the end papers, which often have a coating of dust, especially when the covers do not fit closely, and, if the top is gilt, wipe that carefully also. An uncut top is freed from dust by brushing with a soft brush. The book is then collated to make sure that every page is in place and, if there are plates, that no plate is missing. This operation, it is perhaps needless to say, should by all means be done before purchasing, unless the book comes from a reliable dealer to whom an imperfect copy could be returned. If, in collating an old book, the amateur discovers that page 173 follows immediately after page 136, he need not necessarily be alarmed, as mistakes in pagination and even in the numbering of signatures are very common in books printed a century or more ago. In such cases, the catch words which generally appear at the bottom of the pages, or else the text itself, should be examined to see whether the page, without regard for its number, is really in its proper place or not. Each page is then examined for dirt or finger marks, which can almost always be removed, the quality of the paper permitting, with a soft pencil-eraser or bread crumbs. Marginal notes, especially in contemporary hands, are much better left alone; they are often of considerable value and, when neatly and not excessively done, rather add to the interest of the volume without detracting from its value to any great extent. On which subject Bonnardot has quite a little to say, in the chapter on Stains included in this volume. Presentation inscriptions in the autograph of the author or of some one intimately connected with him of course greatly increase the interest and value of the book. Names written on title-pages can often be effaced by the process elsewhere described, but these should not be disturbed until they have been thoroughly investigated. A name which at the moment seems totally unfamiliar may sometimes be found of special interest inscribed in the particular volume in which it is found. As an ordinary illustration of this, might be mentioned a copy of Edwin Arnolds Gulistan bearing on the half-title the inscription To dear Mrs. Stone from Tama. This author had, at one time, married a Japanese girl, and a little investigation revealed that her name was Tama KuroKawa. Her inscription, of course, remains undisturbed, as it adds a distinctly personal note to the volume. But alas! the John Diddles and William Bubbles who have for centuries scribbled their odious names over fair title-pages, with never the grace to make themselves immortal and their autographs a find!
