You'll find this book useful if you ever need to analyze, interpret, or categorize strategies. It ties together strategies across different domains and shows the commonalities between them. It is a good source of ideas for further work in this new field...as the coverage is broad, it gives a view of the lie of the land without making too many claims. It's also a very portable book, kind of like a book on trees/stars/birds that you might take on a camping trip.
