It has been known from textual sources for some time that besides clay tablets, the traditional writing material in the Ancient Near East, wooden writing-boards were also used by the scribes.M. San Nicolò first drew attention to the fact that writing-boards were widely employed in temple and palace administration in Mesopotamia in the first millennium B.C. and the textual evidence gathered by him was soon to be confirmed archaeologically by the discovery of several such writing-boards at Nimrud. Equally, the existence of wooden writing material in Hittite context has long been established, but no example has ever been found. It is generally thought that private and economic records which are almost totally lacking in the archives at Boǧazköy must have been written on perishable material.The elusive nature of wooden writing-boards manifests itself not only archaeologically by the unlikelihood of their survival but also by the fact that, as a rule, they deserved little mention in the cuneiform texts. Consequently, the quantity of wooden writing material that may have been in use and did not survive is impossible to gauge. Similarly, it would be unwarranted to deduce that centres whose archives have not contributed to the subject, were unfamiliar with writing on wood.
