Robert J Van RisseghemThis book has been formatted with interactive links utilizing Quick-Response (QR) codes. Having direct links to Internet content adds significant value to this subject matter. I recommend that the reader of this book open and view the links as they ecounter them. This provides additional information which supports my understanding of the specific topics I am presenting. This method enables a variety of authors' information to be presented in their own creative format, including documents and videos. It is my hope that the reader will have a more interactive experience, by accessing these QR codes. All the links are accessible on the public domain of the Internet, which can be removed or replaced by the creator and/or publisher of these works. These documents and videos are independent of this author's control and copyright. Read More Read Less
