Where can one find german literature & text books?

Personally I feel bored with German cl...I want some harder higher level text books...like a level for 3rd or 4th year of college? Also, where can I find George Orwell's 1984 in German? One last question, seriously, *trys not to yell out of frustration* is there ANY books on German-Bohemian dialect?! I seriously want to learn the dialect, but it's even stumped my teacher so he can't really teach me it.
