besparer

A besparer is a small, often ornamental, metal object typically used to hold and secure the pages of a book or document. Besparers are commonly found on the spines of older books, particularly those with stiff covers. They are usually made of brass or other durable metals and are attached to the cover material, often by small nails or rivets. The primary function of a besparer is to prevent the edges of the book's pages from becoming worn or frayed over time, especially when the book is frequently handled or stored upright.

The design of besparers can vary significantly, ranging from simple, unadorned strips to more elaborate shapes featuring embossed patterns or decorative motifs. In some cases, besparers might also include a small loop or hole, which could have been used for attaching a chain or a tag. While they were more common in earlier periods of bookbinding, besparers are now less frequently seen on modern publications, partly due to changes in book construction and materials, and perhaps a perceived decline in their necessity. However, they remain an interesting detail for collectors and enthusiasts of antique books, offering a glimpse into historical book preservation techniques.
