A book of this type cannot be prepared with any degree of authority without the help of people in the industry. Some eighty organizations, too many to list individually, in the United States and in Europe provided me with the information needed to ensure that everything I wrote was up-to-date and in line with the latest thinking in the industry. In addition, I gleaned a lot of information from the magazines and books listed in Additional Resources at the back of the book.

I would like to thank each and every one of you who helped me and who took the time to respond to my requests for information and to answer my questions. Thanks again.
