If you are speaking of 'Rise and Fall of the Third Reich', as long as you are aware of the author's bias, it can be an excellent source of information. It's a very good place to start for an overview of the period.
best book ever on the subject is “coming of the third reich” its the first of a three part series, the second being “third reich in power”. i dont think the last on eis out yet.
coming of the third reich is the only book i read that really explains why and how the nazis were able to come to power. pretty intersting. a lot of lessons there for USA.
