Not many people are aware of the extension school system in the United States, let alone the Ivy League; especially Harvard University.
But Michael Shinagel, one of the longest serving deans in the Harvard Extension School, has written one of the most impressive books on the value of the extension school system.
In fact, this book is a must-read for anyone who takes the extension school system seriously, since it is proliferating beyond the world, helped on by the onset of telephony technology and virtual reality. In the near future, the extension school system will be a disruptive technology. This book provides a glimpse of how Harvard University has done it at least since 1909.
