I bought this book with some amount of trepidation. I needn't have worried -- FrameMaker 7, The Complete Reference is one of the best instances of the Complete Reference series.
Too often the Complete Reference series of books consist merely of an item-by-item listing of menu options with no additional insight or explanation offered. Think of trying to learn the English language by reading a dictionary and you'll get the idea.
Happily, the FrameMaker 7 Complete reference is a different story. It provides a comprehensive list of the Windows, Apple, and UNIX variations of FrameMaker's menus and commands, but also adds a lot of value in terms of explanations and examples.
In addition to information helpful to a new user of FrameMaker, there are some truly esoteric features and tips that even I -- a daily user of FrameMaker for nearly five years -- found informative and helpful. The book also contains the best single source of information about FrameMaker 7's new Structured Document commands that I've found so far.
If you're a serious user of FrameMaker, and are looking for a third-party book to augment Adobe's documentation, this is a book you'll use and enjoy. Seriously.
