# nt.number theory – Reference for behavior of Artin \$L\$-functions at \$Re(s) = 1\$

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.
