Note To Our Readers

About This Electronic Book:
This electronic book was initially published as a printed book. We have made many changes in the formatting of this electronic edition, but in certain instances, we have left references from the printed book so that this version is more helpful to you.

Chapter Notes and Internet Addresses:
We have done our best to make sure all Internet Addresses in this electronic book were active and appropriate when this edition was created. However, the author and the publisher have no control over and assume no liability for the material available on those Internet sites or on other Web sites they may link to. The Chapter Notes are meant as a historical reference source of the original research for this book. The references may not be active or appropriate at this time, therefore we have deactivated the internet links referenced in the Chapter Notes.

Index:
All page numbers in the index refer to pages in the printed edition of this book. We have intentionally left these page references. While electronic books have a search capability, we feel that leaving in the original index allows the reader to not only see what was initially referenced, but also how often a term has been referenced.
