A library is an institution that collects, sorts out and collects books and materials for people to read and refer to. As early as 3000 BC, libraries appeared. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education.

According to the archaeological findings, we know that the earliest library in the world is Nineveh Library in Mesopotamia Plain (which was founded by Ashubeniba, king of Assyria, so it is also called Ashubeniba Library). This is the most complete, largest and complete ancient civilization site library excavated today.
