As the main body of work is rather short, Norton have allocated 3/4 of this book to (their usual) in-depth supplementary material. As always, the information provided gives the reader relevant context without the need to obtain the sources separately. This is much better than providing the work in isolation, and allows for a greater appreciation of it as a whole.
Note: I do wish people would stop leaving one-star product reviews for the service provided by Amazon/private sellers, and for Amazon's equating a different format to an entirely different product (when selected from a particular product page). These concerns should be addressed to the company directly; not left as a misleading 'review' of the actual product.
