Fantastic book, I've been referring to this for nearly 10 years now since it first came out. Working as I do with many different cultures, and given the track record of my American Colleagues who don't know where Canada is (joke!) I've always found it ironic that it was an American team who wrote this book!
Anyone who is ever sceptical about the value of its content, I show them the pages for their Country, and within minutes they're sold on its value, even if there's something minor in there they can quibble about.
I especially rely on this book for the Business Practices (Appointments, Negotiating & Entertaining) and the Protocol (Greetings) sections.
I've worked in over 30 Countries, and this book has never let me down. The only times I've needed a Country that wasn't in the book was for Austria & Croatia, but you can't have everything!
