Board Reattachment: Cord Extensions | Current Projects



By Rachel Day
The inherent structure of a book as an object with moving parts means that the stress of use is concentrated in areas. One of the main areas where this occurs is at the joints, especially the upper joint. When the stress gets too much the covering material may split, the sewing supports may break or both of these things may happen. If this happens and the spine piece is still intact this can be a difficult thing to repair on anything other than very small books. One way, a method that may be necessary on very heavy duty volumes, is to remove the spine piece as carefully as possible and work from there. However, there is a less invasive and much quicker method of board reattachment that can be carried out with only minor disturbance to the spine; this is the process of sewing cord extensions.
Two variations on sewing cord extensions will be discussed here. The first is the less invasive but also weaker version of the technique. This treatment is the most efficacious when used either on relatively small volumes or as reinforcement over cords that are still partially intact.
