Query: More a basic dictionary than a guide to style and usage

I was somewhat surprised that any publisher would consider this text a guide. Basically, it is formatted like a dictionary with various business-related vocabulary listings and their definitions. Usage applies to the spelling and capitalization of the listings. My expectations were that this book was similar to a Chicago Manual of Style within a business writing context that includes recently created words germane to the business world. Unfortunately, it isn't useful in this regard. For example, if you want to find out how to use colloquial business language such as "leverageable", you probably won't have much luck with this text as such words appear to be absent....Lastly, the organization leaves something to be desired as the usage topics such as Abbreviations are mixed in with the vocabulary entries, which essentially is the entire book. I really see very little value in acquiring this book...
