PREFACE.

Nowadays the bookbinder does not bind only those books given to him for this purpose as was the case in former years, for present conditions necessitate his undertaking many kinds of work which have little or nothing to do with the binding of books, particularly such as are connected with the making or finishing of printed matter and paper goods, or where pasting, gumming, and glueing are required, which, in their turn, are connected with paper and cardboard.

On the other hand, some branches of the bookbinder's craft have now become quite distinct, and have developed into special industries, and have so enlarged and extended that even their particular methods of working and technical terms have quite changed. Cardboard goods, leather goods, photo albums, maps, and even account-books are treated by particular firms as specialities.

As we must now keep within clearly defined limits, we shall treat here only the work of bookbinding proper as far as it is concerned with the making of the book for publisher, bookseller, and buyer, and also the making of account-books, whilst the other work given to the binder, commonly called fancy goods, must be excluded. Editions de luxe, charters, illuminated addresses, &c., are likewise excluded, as they are quite apart from the ordinary work of the bookbinder, belonging solely to artistic bookbinding. When any such work is required the intelligent worker will not be at a loss; besides, he will derive ample assistance from the illustrations for this class of work.

The parts of this little book have been so arranged as to correspond to our present-day division of work: preparatory work, forwarding, covering, and finishing. In England and France the various processes have for a long time been similarly termed, and although in Germany we could not follow their lead without any deviation, because our method of work and division of labour are so different, yet the basis of this arrangement has been used in this book.

Every text-book has some drawback, the greatest of these being that a practical demonstration on the subject is more helpful than the most detailed written description, and yet even in the latter a text-book is limited. For the rest, I have tried to be as brief and clear as ever possible and to avoid faults which I have discovered in my former writings of a similar kind.

INTRODUCTORY REMARKS ON WORKING METHODS AND MATERIALS.

The bookbinder works with quite a large variety of materials which are mostly what we might call half-made, that is to say, such materials as have already undergone some hand or machine process in order to make them fit for the work of the bookbinder. This is not the place to go into details as to the source of all these materials or the manner of their production: that may be seen in special treatises.

We separate into various groups the materials we use.

A.—Materials for Sewing and Pasting.

The bookbinder himself prepares his paste from wheaten flour and boiling water. Put in a shallow vessel, by preference a stone or enamelled metal wash-basin, the quantity of flour required for about eight days, pour in as much water as will make a mixture by soaking and stirring of the consistency of honey. Add to it boiling water, first slowly, then quicker, stirring all the time. It does not do to add the water too quickly, as that is likely to make the paste knotty or lumpy, because it cannot be stirred quickly enough and the gluten develops unequally. If added too slowly, the starch is not heated quickly enough and does not thicken sufficiently or not quickly enough, and the paste turns out too thin.

Good paste, when cold, should not be stiff like pudding, but should be easily worked with a brush. In order to prevent a skin forming on the top whilst cooling, pour over the paste as much cold water as will cover the surface immediately after the mixing with the boiling water; this water is afterwards poured off.

In summer when the paste is made, and whilst still hot, add a few drops of turpentine and mix well; this preserves the paste and keeps off insects. The addition of alum to the paste tends to make it watery, besides having no preservative properties.

If required, paste may be thinned by adding a little warm water. Potato flour is often used fraudulently for making paste, but this should only be taken when it is possible to use it up quickly, and not for books, but only for fancy goods, as this flour does not possess great adhesive power and is unsuitable for leather.

Glue is made from the well-known cake glue. The best English glue, although the dearest, is the cheapest to use. Good glue whilst soaking in water should still retain a certain degree of stickiness, must not be greasy, and should have no disagreeable smell. Glue if weighed before soaking and afterwards dried and again weighed should give no perceptible loss in weight. Good glue should not have a disagreeable taste, and above all should not betray the presence of salt.

To obtain the proper consistency in glue for bookbinding, a quantity of the cakes is taken and sufficient water poured over it to cover well. The next day the gelatinous mass is taken out of the water and dissolved in the glue-pot by placing the softened glue in a pot standing in an outer vessel containing boiling water. Glue should never be boiled nor placed directly on the fire, as that causes the loss of the best part of its adhesive property.

Glue and paste are generally worked with a brush. For paste a large hollow brush is used; this holds a large quantity of paste and covers a large surface. For glue a closer brush with a metal fastening is used, because here the hairs cannot be secured with pitch owing to the brush being constantly exposed to heat. On the paste brush there must be neither ring nor anything else of iron, as this used in paste would cause rust, and rust would give iron stains to light-coloured leathers. For the same reason no enamelled vessel should be used for paste after the enamel has once been chipped or worn.

Laying the glue or paste on a material is called glueing or pasting. A zinc-plate is the most serviceable pasting-board, as the paste is easily washed off. Glue can be scraped or soaked off and used again. Pasting-boards of mill-board or paper are hardly to be recommended, as their use entails a considerable loss of material.

Of other adhesive substances, dextrine, gum, gelatine, and isinglass are used for certain purposes. The two former are always used cold, the two latter warm. The former are dissolved in cold water; gelatine and isinglass are soaked exactly like glue, the water poured off,
