Origins and antiquity
Writing is a system of linguistic symbols which permit one to transmit and conserve information. Writing appears to have developed between the 7th millennium BC and the 4th millennium BC, first in the form of early mnemonic symbols which became a system ofideograms or pictographs through simplification. The oldest known forms of writing were thus primarily logographic in nature. Latersyllabic and alphabetic (or segmental) writing emerged.
Silk, in China, was also a base for writing. Writing was done with brushes. Many other materials were used as bases: bone, bronze, pottery, shell, etc. In India, for example, dried palm tree leaves were used; in Mesoamerica another type of plant, Amate. Any material which will hold and transmit text is a candidate for use in bookmaking.
The book is also linked to the desire of humans to create lasting records. Stones could be the most ancient form of writing, but woodwould be the first medium to take the guise of a book. The words biblos and liber first meant "fibre inside of a tree". In Chinese, thecharacter that means book is an image of a tablet of bamboo. Wooden tablets (Rongorongo) were also made on Easter Island.

Clay tablets were used in Mesopotamia in the third millennium BC. The calamus, an instrument in the form of a triangle, was used to make characters in moist clay.

This presupposes a degree of organization with respect to books, consideration given to conservation, classification, etc. Tablets were used right up until the 19th C, in various parts of the world, including Germany, Chile, and
