<strong>The Landscape of Man</strong> by Geoffrey and Susan Jellicoe.

I've been trying to work my way through this book for a while now; it's one of those books that are supposed to be majorly influential in one's career in landscape architecture and environmental planning. I'm not sure I understand why, though, as it's all material I already learned. I could see the book being useful as a "textbook" for landscape architecture history classes, but I probably won't go through it again once finished.
