This book has been on my National Geographic Society shelf in my home library for 37 years. I used it for reference when planning vacations before the internet made finding information easier. I finally read all the text this year.Sometimes the text and information are dated. Sometimes the pictures are dated too. People may be in pictures for interest or to show scale, but the short shorts, tube socks and permed hair cuts occasionally date a picture.The book can still be used to begin research or armchair travel.
