I just got a few books in that seem like very promising pieces of work for a bibliography. I wanted to recommend them and encourage you guys to recommend anything that you think is particularly good. I ask that you put down the full citation and a brief blurb on what the book is about.
Hawkes, Jacquetta. The Atlas of Early Man. Dorling Kindersley ltd; London, 1976.
This book discussed the development of man from 35,000 BC to 500 AD. There's a lot of good information, maps, and pictures of art/technology/weapons/etc.
Haywood, John. Historical Atlas of Ancient Civilizations. Penguin Books; London, 2005.
This book is set up a little differently than Hawkes' book. It's divided by region and then in chronological order. There are a lot of great maps, good information, and pictures.
Noorbergen, Rene. Secrets of the Lost Races. Bobbs-Merrill Co; New York, 1977.
Noorbergen wrote this book after reading Chariots of the Gods. He discusses "out of place" artifacts from ancient civilizations with a focus on technology.
Kramer, Samuel Noah. The Sumerians. Their History, Culture, and Character. University of Chicago Press; Chicago, 1963.
This is one of the best general histories of the Sumerians that I have come across.
