Books Paper making in Europe had begun around the 11th century, up until the beginning of 16th century vellum and paper were produced congruent to one another, vellum being the more expensive and durable option. Printers or publishers would often issue the same publication on both materials, to cater to more than one market. Paper was first made in China, as early as 200 B.C., and reached Europe through Muslim territories. At first made of rags, the industrial revolution changed paper-making practices, allowing for paper to be made out of wood pulp. Paper made from wood pulp was introduced in the early-19th century, because it was cheaper than linen or abaca cloth-based papers. Pulp-based paper made books less expensive to the general public. This paved the way for huge leaps in the rate of literacy in industrialised nations, and enabled the spread of information during the second industrial revolution. However pulp paper contained acid, that eventually destroys the paper from within. Earlier techniques for making paper used limestone rollers, which neutralized the acid in the pulp. Books printed between 1850 and 1950 are at risk; more recent books are often printed on acid-free or alkaline paper. Libraries today have to consider mass deacidification of their older collections. The proper care of books takes into account the possibility of physical and chemical damage to the cover and text. Books are best stored out of direct sunlight, in reduced lighting, at cool temperatures, and at moderate humidity. They need the support of surrounding volumes to maintain their shape, so it is desirable to shelve them by size. |
