Libraries came up only when literacy increased. However, from earliest times, human beings liked to record their achievements and their importance. In Southern Iraq, archaeologists have discovered the remains of libraries of clay tablets which were written about two thousand years before the Christian era by the Sumerians. Similar libraries have been found in excavations in the old cities of Turkey and Syria. Markings on these clay tablets preserved in museums around the world have not yet been interpreted. Also baked clay, bone and wood were used in very early writings.
The public library has originated in the ancient Greek civilization. Papyrus scrolls were used for writing. As Greek influence spread through Asia Minor, Palestine and Egypt, great libraries were established in important cities.
