The book is setup just like a Dictionary with all the common Deities of Ancient(Sumer and Akkad only)Mesopotamia. All definitions have reference to other terms listed in bold letters somewhere in the defining paragraph. This makes cross referencing terms an easy goal to accomplish. The book does not include Egyptain, Canaanite, or Hittite Deities. However, there is a great companion volume to "Gods,Demon,and symbols in Ancient Mesopotamia" called "Dictionary of Deities and Demons in the Bible" edited by Karel Van Der Toorn and for a complete book of all the Canaanite gods and stories that are availible try "Canaanite Myths and legends" by John Gibson. I have all three and they are a must for anyone doing research on the Ancient gods of The fertile Crescent.
