University of Pittsburgh at Johnstown, USIntellectual depth is a strength –the intellectual history is important here and well covered. The inclusion of teaching materials and the expansion of such materials in the proposed 4th edition would be a huge asset. Professor Robert O. Vos, University of Southern California, Dornsife, USMany topics are covered. It is difficult to find a textbook that isn’t too focused on a narrow aspect of urban sustainability, or one specific region of the world. Many perspectives are represented, both historical and contemporary, Jennifer Rogalsky, State University of New York Geneseo, USI think the biggest strength is the combination of classic and contemporary readings.Professor Carlos E.
