Methods and Materials
Most library binders use a method of bookbinding called oversewing to secure the volumes. Oversewing involves cutting or milling off the spines of the volumes, creating a block of loose pages. Then the loose sheets are combined into small units or signatures, which are secured with overlock stitching. The separate signatures then get sewn together, creating a single book block. Often a piece of linen is glued to the book block spine for further support. The spine of the volume sometimes is rounded and backed to keep the spine from caving in. But if the paper of the volume is too fragile, or the book block is too thick, the spine is left flat. The book block is placed in a sturdy cover or case, with special paper covering the inside covers (Boardway 1993).
The most common cloth used by library binders to cover the boards of the book is buckram coated with acrylic. Acrylic coatings are generally resistant to water, mold, insects, and ultra-violet light. The buckram used is a 100% cotton, bulky fabric designed to withstand wear and tear (Jones 1993). Smaller books may be bound in c-cloth, a lighter weight cloth that may or may not have an acrylic coating. The information about the volume (such as title and call number) is hot-stamped onto the spine. Bound serials are typically all bound in the same color of buckram, in order to indicate the relationship of the volumes.

“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
