Ok, so im a 18 year old student, who is currently writing my Personal Study for a History A-Level and im studying the Siege of Leningrad and i came to Amazon to pick up some literature on the subject, i bought this book and "900 Days the Siege of Leningrad" By Harrison E Salisbury
This book is much more of a easier text than the Salisbury's. It has many more pictures and maps, which is very helpful in order to get a feel for the actual Siege. It is however a lot less concise. It has less background and gives less time to the German tactics during the Siege. I have affectionatly given this book the nickname "The Idiots guide to the Siege of Leningrad", but that IS in comparison to Salisbury's book
My Basic advice is...
If you are studying this subject then buy both, they are both incredibly useful texts, for diferent reasons. This book is useful for attitudes during the Siege and for maps and pictures (it sounds childish but you really do need to see the Siege from a visual perspective to believe some of it)
However, if you do not wish to purchase noth texts for whatever reason, then Salisbury's book is the better purchase, it has so much infomation in it and it is more helpful for the person who is studying this subject
