Like all compilation books it is OK for planning a trip to the area, but short on information when you get there. It does save carrying loads of books around. It is now badly out of date. A new book is due soon, apparently
I used this for a recent trip to Africa. The only issue is that it's almost impossible to go that much in depth when trying to cover all those countries. Was the only guide I found that covered most countries I was going to (Zambia, Zimbabwe, Botswana and South Africa) and gave me some basic overview of these countries.
