This is lavishly illustrated book that I suspect will appeal more to those who are thinking about where to start diving. It is really a coffee-table book. More serious divers are more likely to pick up a copy of the "Diver Travel Guide". The "Diver Travel Guide" is updated annually or at least very regularly. I'm fairly sure that I picked up a complimentary copy with "Diver" magazine but it can certainly be bought separately.
The "Diver Travel Guide" provides a concise description of each destination followed by a fact file which summarises the relative cost; water temperature and an indication of what thickness wetsuit to wear; visa requirements and inoculations. To be fair, similar information (though less detailed and nothing on relative costs and innoculations) is included as an appendix to the "Dive Atlas".
If what you are looking for is some inspiration about where to go diving you could do much worse than get a copy of "Dive Atlas of the World".
