If one is on the verge of taking a trip to Poland and other countries in easter Europe to see what is left of the Jewish communities, there is no better preparation than this book. Not only does it provide an overview of what remains in all these eastern European countries, it also gives detailed information of where to look and what to see in each city. While it is an excellent tourist guide, it also provides history. There is also a section setting out where to get more information about each village (and there were so many of them!). This is Ruth Gruber's second book on the subject. It is more comprehensive than the first and is certainly worth the money. If you are planning a heritage trip to find your ancestors, don't leave home without it. I found it invaluable.
