Can someone give me some information and possible sources regarding some short and long term affects of nazi control over literature and art etc, as well as how the ideas and beliefs of members of German society changed as a result of Germany being 'culturally stunted' due to this control?

Any help would be much appreciated :)
Thanks!

Here is some good background reading on the subject.
