This is the kind of book you might find in a museum gift shop. It is short, at only about 100 pages, and half of those are illustrations, so it is very much a brief introduction to the topic. On the other hand, the photographs are gorgeous, detailed, and full color on glossy paper. Most of the items shown are from the British Museum.
The book begins with a section on the development of cuneiform, its amazing longevity across thousands of years, and it adoption for writing by linguistically unrelated languages from Syria to Iran and Anatolia to the Levant. There is even speculation that it influenced the early development of the Minoan scripts. It was originally developed by the Sumerians, whose language seems to have been unrelated to any other, from an earlier purely pictographic writing system approximately 3200 B.C.. The astonishing flexibility of cuneiform is shown by its ability to adapt to language families entirely unrelated to Sumerian, such as Semitic (Akkadian), Vannic (Urartian), Indo-European (Hittite), and other language isolates such as Elamite, Hattic, and Hurrian. The latest cuneiform tablet found so far is from 62 A.D.
It was a complicated writing system, which could take years to master. Depending on the language it was being used for it usually contained 800-1000 signs, some for whole words, some for syllables, and some for determinatives (in English percent and dollar signs are determinatives, indicating that a number is to be treated as fractional or as currency). However, like modern Chinese, not all of the symbols needed to be known to achieve basic literacy. It is estimated that most people could function by knowing only 100-200 of them.
Part of its longevity was due to the simplicity of its materials: river mud and a cut reed. Most of the tablets which have been recovered were intended for temporary record keeping, such as recording the receipt of goods or payment of taxes. More formal uses included magic spells, religious rituals, royal proclamations, and even the earliest known literature. The tale of Gilgamesh is known to us from the cuneiform tablets it was was first recorded on. Also, unlike paper or parchment, these tablets can last thousands of years under the right conditions. Fire, in fact, actually improves them by baking and hardening the clay. This is good because the history of the region is a bloody tale of the rise and fall of dynasties and empires, conquest and slaughter, with cities conquered, burned, and razed over and over.
Writing and empire go hand in hand. Civilization could not grow beyond the village level until there was a way to administer larger political units. With writing and the ability to keep track of people and goods, the span of control of kings greatly increased, and the first empires arose, leading to increased trade, standardized laws, and political and religious unity. The transition from hunter-gatherers to farmers and pastoralists had taken place thousands of years earlier, but it was only with the invention of writing that the first civilizations arose and the long march to the modern world began.
