I found several inaccuracies, such as restaurant names misspelled or maps showing hotels on the wrong side of the road, but nothing seriously wrong. The history and culture sections were adequate for the general visitor, and for most of the historical sites there was enough detail to save you having to buy separate guide books for each attraction. In Palermo, hotel listings were rather brief, and it may be better these days to search on the web, but out in the villages there were some useful recommendations. Town maps were generally adequate (though rather small scale: you need good eyesight) but I would suggest a proper road map as well if you are doing much travelling about by car. All in all, a useful book; it's difficult to see how it could be improved significantly without getting bigger and heavier; but others are probably as good.
