Rebacks (Cloth and Leather)
This is one of the most common types of damage to books is on the spine. The cloth or leather can break along the joint (where the cover opens) and eventually the material can completely fall off the spine and become lost. The major cause for this is that most people pull a book from the shelf by the top of the spine. This causes damage to the caps, endbands and joints.
A reback replaces any missing covering material and reattaches the spine to the book. The sewing and board attachment should be sound and are not disturbed. Depending on the book, either bookcloth or leather maybe used to match the original. Bookcloth and leather are both strong binding materials, but it is often hard to match the original bookcloth and leather is expensive and time consuming to work with. For this reason, some repairs are done with Japanese paper and/or cotton muslin instead. These materials can be dyed with acrylic paints and match the original almost perfectly. In either case, as much of the original which can be saved is reused for the conservation treatment.
