This is NOT the Fodor's Israel guide. It's the supplement with historic, cultural, and political coverage. As such it's a fascinating read with lots of spashy colored photos.
It's easy to get confused, but this a SUPPLEMENT to the Fodor's guide! It does not contain info about attractions or logistics and isn't intended to. It's laid out by time periods, regions, and topic (such as who the people are.)
Even for someone who's been there before, I found details I didn't know. It enhanced my trip beyond the short paragraph summaries every guide book has for each attraction, and lead me to notice items I wouldn't have otherwise. ...such as the demographic diversity, and more understanding of the religious hodgepodge of people. The layout of the history, as a reference, helped me make more sense of sites I'd seen, since there is an endless array of history in that country.
For the cultural aspects I was familar with, most of the info is reasonably accurate. There's always room for argument with everything, but mostly they do a nice job of summing up topics. It appears to have a Christian editorship based on some of the information focus on Crusades and such, but not offensively so. It doesn't attempt to cover Arab angles all that much (on the modern history), and could be argued with, but it does talk respectfully when it does.
(As for the inaccuracies... The short topic summaries sometimes used classic but is superficial "history lines" that aren't very accurate. For instance, comments that the founders were aethists, which doesn't begin to understand their relationship to the religion. But only a knowledgeable reader will absorb or notice this within, the intense amount of info presented in a small space.)
What's striking is that it's easy to read and absorb a lot in compact wording. The photos make it fun. There's something very well designed about the layout and intensity of research that makes it... much more interesting than the usual "picture travel books" that are fluffy.
It's a very fun supplement, and you'll get to look at and understand more than you would, with the straight guidebooks' with their info about sites and logistics.
