Description
This is a tight-back case binding covered with thin blue paper over thin pulp-boards with rounded corners. The textblock is a cross-grain thick, machine-made cream paper. The text has been printed with black printer's ink and there is a slight type impression. The textblock was sewn over sathe time of examination.

Condition
The binding was previously repaired with a strip of black book-tape placed over the spine. The tape has become desiccated and the boards are detached from the textblock. Both fly-leaves are detached from the textblock as well as the boards.

Before Treatment: Ambient light.

After Treatment: Ambient light.

1. The spine was cleaned with a poultice of methyl cellulose.
2. The original grooves used for the sawn-in cords were deepened and emphasized with a small file. New cords were placed into the grooves and glued in with wheat starch paste.
3. A spine lining of Japanese kozo tissue was applied with wheat starch paste and pressed into the grooves with a bone folder. A second, overhanging textile lining was applied with PVA. New double-folio endpapers of 70lb Mohawk paper were sewn on through the textile lining and anchored by sewing into three signatures into the textblock. A third paper lining was then applied with PVA.
4. New boards were cut and shaped with rounded corners to match the original boards. A groove was cut out of the spine-edge of each board, so that the textile lining flange and cords would lie flush. The boards were reattached by gluing the textile down with a mixture of paste and PVA onto the outside of the board, in the groove, and then gluing the cords onto the textile flange.
5. A spine piece was made of double-thickness Moriki tissue and a 20pt spine stiffener. The spine piece was attached to the boards with PVA, and the turn-ins folded over the board edges.
6. In the manner of a quarter-style binding, each board was then covered with another piece of single-thickness Moriki tissue, leaving a small 1 cm-wide strip of the spine piece visible at the spine-edge of each board.
7. The corners of the new endsheets were rounded prior to being pasted down.
8. A new spine label was created and pasted to the spine using wheat starch paste.
