The earliest royal library in the world can be said to be an archive established in the capital (now Anyang, Henan Province) in the Yin Dynasty of China in the 5th century BC/KLOC-0. It contains Oracle Bone Inscriptions, which is of historical value for the reference of rulers. This can be regarded as the bud of the Royal Library. The royal library with historical records appeared in the era of Emperor Wu of the Han Dynasty more than two thousand years ago. At that time, the government issued an announcement to collect books, and set up a library for books in the palace, equipped with officials in charge of books.
