I used this book for my travel to Saudi Arabia following the footsteps of Nassir Khusraw, the Persian poet and philosopher who went to Mecca in 1045. According to this book the distance between Medina to Jeddah and Mecca is 390 and 410, respectively. Nassir Khusraw in his "Safarnameh" says the distance between Medina and Mecca is 100 Farsang (about 600 kilometer). I was wondering why he overstimates the distance. In my book, then I added a paragraph explaining the reasons and theorizing that he might have travelled a longer route, due to dangers on the road and search for water. He was always correct in his estimation of the distance between many cities he travelled. Then I found out about MSN Encarta World Atlas. I typed the name of these cities and found out the distance was 629 and 605 kilometer, respectively.
Well done Nassir Khusraw a millenium ago! and Mr. Robison, correct this big mistake as soon as possible. The book has little practical use as far as Mecca and Medina is concerned

First of all this Iranian guy is correct. The official name of this body of water is PERSIAN Gulf. The term Arabian Gulf was invented in 1970s by some Pan Arabists who failed to show up at their geography classes. The author's use of this term shows simply his arrogance and fact that he does not know the region nor its people. By using "Arabian Gulf" he simply wants to impress ignorant Arabs into buying his book.

Other than that his book is useless as it does not touch on the cultural aspects on the region.
