At Nineveh, 22,000 tablets were found, dating from the 7th century BC; this was the archive and library of the kings of Assyria, who had workshops of copyists and conservationists at their disposal. This presupposes a degree of organization with respect to books, consideration given to conservation, classification, etc. Tablets were used right up until the 19th century in various parts of the world, including Germany, Chile, Philippines and the Saharan Desert.[1]
