Leather binding causes damage to the paper.
Answers
Answer:
There are many reasons why bindings begin to fail. A small percentage of these can be attributed to poor workmanship and inappropriate choice or quality of materials used during the initial binding process; the vast majority, however, can simply be chalked up to the ravages of time.
Though robust if constructed well, books are not interminable. Their longevity is dependent upon a variety of factors, environmental conditions in particular. Air pollution and extremes and fluctuations in both temperature and humidity can rapidly accelerate the deterioration of glues, paper, cloth and leather. Cloth and paper are also highly susceptible to photolytic damage caused by excessive exposure to light. Insects and rodents, too, are attracted to paper and glues, and will steadily munch their way through a bevy of books given the chance.
These are fairly obvious accelerators though. There’s another worthy of mention here. Less apparent but frequently more insidious, the human being can be rather rough with books. We bend their covers beyond 180 degrees, we crush their spines under copiers and we dog-ear and mark their pages with indelible inks, foodstuffs and beverages. It’s not easy being a book. Many years ago, I worked in a Library to which a patron returned, somewhat sheepishly, a borrowed book. Having accidentally driven over it (whilst open) with their 4x4, its front and back covers found a new “bitumen grain” and its pages, the latest design in rubber tread. Fortunately most damage suffered at the hands of humans is inadvertent. Readers can’t help but frequently handle a popular book, and they really do mean well when they attempt a ‘repair’ which conservators know will only compound the problem; perhaps even create another one. Even binders have embraced new materials and techniques which have later proven catastrophic. Need we mention Caoutchouc? (refer Sewing cabinet) At the time, though, these ideas were innovative, they sped up the binding process considerably and allowed publishers and booksellers to meet an unprecedented demand for books.
Thankfully, today's skilled binders and paper conservators know just how to correct those well-meaning but inexperienced repairs and they are experts at addressing the various ravages of time.
