Mesopotamian Witchcraft – Towards a history and understanding of Babylonian Witchcraft Beliefs and Literature is an interesting book, published in 2002. It is special in that it makes a distinction between the religion and religious (read state/socially motivated) concerns, and magic that is more practical and medicinal. It also gets into some of the specifics of Mesopotamian witchcraft and magic, and the shift in the image of the witch from a cure to a curse.
This one is on my “to buy” list, and so far, from the preview, it is a very good read.
