New Models In Geography V2 [PDF ebook] 

First published in 1989. The publication of Models in geography presaged a sea change in the practice of Anglo-American geography. For a new set of models, this book provides a summary of their nature, spirit and purpose based upon a political-economy perspective. The book is split into two volumes, each consisting of four parts. This makes the title suitable for students and geographers with an interest in models of the city, civil society and social theory.
