It has already been said that the sections are sewn throughout, and, further, that the end section is likewise similarly sewn with them through the linen joint in high class work with colored cordon net silk. All sheets, without exception, are kettle-stitched at the end. Large books are not usually glued up the whole of the back, but only at head and tail, with perhaps a little in the middle; they are only completely glued up after having been rounded in the press, as this makes them retain their shape longer.

If it is decided to do any marbling, the fore edge is marbled immediately after trimming it. Rounding is more pronounced in this than in ordinary work, otherwise the spring back would have no effect with such bulk, and the book would easily go out of shape.

The account book is also pressed, but not in the same way as printed books, as the former has its groove pressed quite out. After careful adjustment between boards, they are squared to the edge of the first and last sheet, the whole lifted into the press, and the back glued with very hot glue. The bands are generally left outside the boards, as they would leave marks too pronounced on the book if pressed inside. After the book has thoroughly dried in the press, it is cut at top and bottom, marbled, or some other suitable treatment given to the edges, and then pasted up. The "clothing up" of the account book is done either with soft leather and paste or with mole skin specially prepared for the purpose; in the former case the bands are omitted, that is, only the parts between the bands are pasted. In pasting up with mole skin, only the back may be glued never the covering material. The covering material has a loose overlap of 4 cm at each side.

Account books take a stronger headband than other books; it must reach on to the board, which it binds to the book. For this purpose the board must first have been affixed.

In the first place, a thin but very strong board is laid about 1 1/2 mm. from the joint-upon the first sheet, which has been completely coated with glue; the bands are pasted out upon this board, as also are the leather or beaver clothing overlaps.

It is obvious that this thin board is not stout enough for this heavy book, therefore a second heavier board-or, if necessary, even a third-is pasted to it; but as the back now goes over on to the board, the heavier board must be set back sufficiently to prevent it from pushing into the back when opening the book.

As the pasting together of these boards makes them very thick, and such thick boards not being easily cut, they are generally cut the required size beforehand. Before pasting the thicker board upon the first board, the back is prepared.

First of all the headband. It is carried on to each board 3 cm deep, and the boards must therefore be cut out the same distance up to the edge; at A the board is beveled off on the inside. Now cut a piece of colored chamois leather dark red or green 5 cm wide and as long as the distance from one notch across the back to the other.
