This book is designed as a guide for the preparation and examination of entries in the TVTyme.net website. Being the compilation of the North American Industry Classification System, the guide can be used for other purposes dealing with products and services prevalent in the North American Continent. Prospectors, traders, merchants, manufacturers, consultants, etc. from all over the world, who like to penetrate certain market niches in North America may find this book a necessary resource. The book is structured such that one is never more than a page away (forward or backward) from the target object of examination. The page header indicates the main sector in the economy. The page footer indicates the subsector as well as the industry group. Automatically, the page header and the page footer change as sectors, subsectors, and industry groups change. The page footer plays a significant role in the search for information. Another helpful feature of the book is how the Table of Contents is structured. Instead of providing a separate page or appendix to summarize the North American Industry Classification System, the Table of Contents provides the information from sector down to the industry group. Being of a small trim size, the book can be carried around handily - on the field, in the office, in park benches, in wherever the reader decides to read it. More interestingly, the book is in Kindle format in addition to being in paperback. This fortifies the reader with enough information without being conspicuous.
