This document provides an overview of important books related to strategy. It discusses the origins of strategic thinking from ancient Chinese military strategist Sun Tzu to European theorists like von Clausewitz and de Jomini. Von Clausewitz viewed strategy as descriptive rather than prescriptive, while de Jomini saw actionable principles as central. Modern classifications of strategic approaches include prescriptive schools like planning and positioning, as well as more descriptive schools focused on learning and culture. Key books that illustrate these include Mintzberg's Strategy Safari and Collins' Good to Great.
