Further Reading
The primary sources for the excavation of Ur are the volumes published by C. Leonard Woolley and others in the years since work at the site ended. The most important of these, as far as this period is concerned, are Volume VII, The Old Babylonian Period (by Woolley and Max Mallowan) which deals with the Giparu and Residential areas of the city and Volume V, The Ziggurat and Its Surroundings which covers the excavation of the ziggurat. These volumes are available at The Ancient World Online.
Also available is Woolley’s popular account of his excavations, Ur of the Chaldees, the most recent version of which has been revised by P.R.R. Moorey in light of more recent evidence.
