In response to Ms. Bogg's review, I am well aware that the Naval Postgraduate School does own photos of the Hotel del Monte. Unfortunately, they have been held in "deep storage" for quite some time, and were unavailable during the time I was putting this book together. However, I used multiple other sources and looked at over 2,000 photos before choosing the final 200. Fluff? Definitely not. I put in 5 move star photos because, like S.F.B. Morse, I LIKE movie stars. And if you want to know who S.F.B. Morse was, please read this book for yourself! All sources are listed in the bibliography and mentioned in the acknowledgment, so those of you interested in reading more about this wonderful hotel can do so.
