Interested in how you stand visiting the 878 UNESCO World Heritage Sites? This book will give you a lot of information but I think you'll be tearing your hair out before you're done. The format is spare (but photos are great) and beyond user-unfriendly. The sites are listed in chronological sign-up order (which head-in-the-clouds beaurecrat thought that wacky order up? and what's wrong with a country-by-country order??) so you have to search the index by country and look up each site on its individual page. AAARGHHH! By the time I found all the sites in Italy, I was ready to kill. If all you want to do is browse, this is okay, but as far as a traveler's resource, this heavy tome is useless. So...give it a 1.
