The textbook for the Cold War course I'm TAing right now, truly phenomenally huge book that is actually global. Reynolds covers an impressive range of places and topics in here. He has really great chapters on global development in which he shows the many varieties of development as well as the sheer scale since 1945. He also has chapters that break from the chronological narrative and explore issues in often under examined areas in these types of books: the genetics and microprocessing revolutions, electrification, urbanization, changes in women's lives, even postmodernism and fundamentalism. This would be a good book for a World Since 1945 class as long as you don't assign the whole thing, which is just a little too bulky. Even if you don't assign it for class, it will make a fantastic lecture aide for hundreds of topics in any modern global history class. Hats off to Reynolds for this beast.
