TITLE: Book/tutorial recommendations: acquiring math-oriented reading proficiency in German
QUESTION [33 upvotes]: I'm interested in others' suggestions/recommendations for resources to help me acquire reading proficiency (of current math literature, as well as classic math texts) in German.  
I realize that German has evolved as a language, so ideally, the resource(s) I'm looking for take that into account, or else perhaps I'll need a number of resources to accomplish such proficiency. I suspect I'll need to include multiple resources (in multiple forms) in my efforts to acquire the level of reading proficiency I'd like to have.
I do like "hard copy" material, at least in part, from which to study. But I'm also very open to suggested websites, multimedia packages, etc.  
In part, I'd like to acquire reading proficiency in German to meet a degree requirement, but as a native English speaker, I would also like to be able to study directly from significant original German sources. 
Finally, there's no doubt that a sound/solid reference/translation dictionary (or two or three!) will be indispensable, as well.  Any recommendations for such will be greatly appreciated, keeping in mind that my aim is to be proficient in reading mathematically-oriented German literature (though I've no objections to expanding from this base!).

REPLY [2 votes]: If your focus includes number theory, then Landau's classic Handbuch Der Lehre Von Der Verteilung Der Primzahlen is an excellent choice. You can easily find a hard copy and/or read it online, for example, at University of Michigan Historical Math Collection
