TITLE: Reference for behavior of Artin $L$-functions at $\Re(s) = 1$
QUESTION [6 upvotes]: Would anyone know a reference that proves the basic facts about Artin $L$-functions at $\Re(s) = 1$? Namely, the non-vanishing and holomorphicity for non-trivial characters.
I assume this was done in Artin's original paper, but a modern source would be most welcome.

REPLY [5 votes]: I also had a hard time finding a reference for this a while back.
