A sheet material used for writing on or printing on.
Paper remained relatively expensive through the centuries, until the advent of steam-driven paper making machines in the 19th century, which could make paper with wood pulp. Although older machines predated it, the Fourdrinier paper making machine became the basis for most modern papermaking. Together with the invention of the practical fountain pen and the mass produced pencil of the same period, and in conjunction with the advent of the steam driven rotary printing press, wood based paper caused a major transformation of the 19th century economy and society in industrialized countries. With the introduction of cheaper paper, schoolbooks, fiction, non-fiction, and newspapers became gradually available to all the members of an industrial society by 1900. Cheap wood based paper also meant that keeping personal diaries or writing letters became universal. The clerk, or writer, ceased to be a high-status job, and by 1850 had nearly become an office worker or white-collar worker , which transformation can be considered as a part of the industrial revolution.
Unfortunately, the original wood-based paper was more acidic and more prone to disintegrate over time, through processes known as slow fires. Documents written on more expensive rag paper were more stable. Mass-market paperback books still use these cheaper mechanical papers (see below), but the more careful book publishers now use acid-free paper for hardback and trade paperback books.
