This is not to say it is a light-weight when it comes to material. There is substantial history and background included. It's enough to satisfy your interest, but not so much that it turns into an overbearing text book.
Equal treatment is given to all three Baltic states: Estonia, Latvia and Lithuania. It guides you though the must see attractions as well as historical spots. As I read it, I felt as though I had a person walking side by side through the various sights.
Another thing I love is their "Yellow Pages" format for the nitty gritty travel details at the back of the book. You'll find all the basics you need to know that all the other good travel guides would offer. Obviously they do this to make it easier to produce new editions, as well as locating all the key facts with an easy to use format.
This book receives my highest recommendation for an incredible travel guide and addition to your home library.
