Book Update: Can Wizards4Word help?

I was just feeling overwhelmed with the management of my book project, Battle Gaming: The New American Sport. I recently decided that chapters 7,8,9, and 10 had to be scrapped and replaced with whole new reorganized set of chapters. The current content looks something like

Part I - Playing the Games
1 - A New Kind of Sport
2 - Safety First
3 - Quick Start Guide
4 - The Games
5 - Combat in Detail
6 - On the Battle Field

Part II - Equipment
7 - What You'll Need
8 - Technology of Foam Padded Weapons
9 - Swords and Long Blade Weapons
10 - Handheld Weapons
11 - Tips and Tricks of Weapon Construction
12 - Thrown Weapons
13 - Archery and Arrows
14 - Shields
15 - Armor
16 - Uniforms and Costuming
17 - Game Props

Part III - Running the Games
18 - The Organizations (Dagorhir, Belegarth, Amtgard, Darkon)
19 - Doing it Your Way - Starting a Club
20 - The Successful Game Day
21 - Building on Success

Each of the chapters are split into multiple section files in word. This has made writing much easier since a section is on a very specific topic and covers only a few pages. The problem is that I now have 37 folders containing 348 files. Even though some are just images and diagrams or research items, I am still having a some difficulty keeping it all organized.

I was checking out the Book Master system (http://www.wizards4word.com/bookmaster.html) that is provided by Wizards4Word to see if that might help. I found a few good reviews, but if anyone has some more information about this product, I welcome hearing from you. Feel free to post a comment. Thanks - Dave
