Paper books were originally in the form of rolls, then folded leaves, and finally bound volumes like the books in use today. There were various methods for the production of early Chinese records. Bone and stone media were engraved or incised with a metal stylus or knife. Wood, bamboo, silk, and paper was written on with brush-pens; the ink was black; usage of ink dates to Neolithic China. Styli were also used and were made of bamboo, wood, horn, and metal, but it is not known when the stylus first came into common usage. Book knives were used as erasers for bamboo and wood tablets but not for inscriptions. Inscriptions on bronze were cast from molds. Inscriptions on clay were made by molds or were impressed with stamps. Seals were used to produce duplicates on soft clays and later on silk and paper. These seals were cast from metals or cut from jade or stone. Before the invention of woodblock printing, inked impressions from stone or other inscriptions would be made by rubbing or squeezing paper over their surfaces. This technique was used up to the early 6th century and led to the invention of printing. Moveable type was invented in China some 400 years before Gutenberg’s press. (1, 202-203)  The period following the collapse of the Han (220 AD) is known as (one of the many) “Dark Ages” and was typified by political strife, wars, and social upheaval. Despite the turmoil of that period, learning and culture continued to grow. Among the intellectual elite and rulership, Confucianism continued to be the dominant philosophy. Taoism and Buddhism emerged as religions and began to flourish. Buddhism, a populist religion, had been introduced to China at the beginning of the Christian Era and quickly became a religion sought after in times of strife by the masses where it was propagated. The first translation of a Buddhist text appeared in China in the 2nd century AD and by the 3rd century the volume of translations had increased a great deal. Buddhism’s influence on literature and scholarship grew in relation to the conversion of the elite and ruler ship. (17)  During the Sui Dynasty (581-618 AD), Buddhism enjoyed an explosion in the production of printed texts. This is partly due to the reunification of the empire and partly because Emperor Wen decreed that all Buddhist texts then in print were to be copied and placed in temple libraries in all the major cities.
