How do Noether's theorems apply to field theory and discontinuous symmetries?

[akai_ma]

ok so I understand the general idea of Emmy Noether's theorems, for every differentiable continuous symmetry there is a correlated conservation. The classical formulation seems simple enough, but the field theory formulation seems nasty. I have been through electrodynamics and quantum mechanics. So my question is this:
Where can I find an in depth understadable formulation of Noether's theorems for field theory?
Also from what I've read the theorems only work for continuous symmetries. What about discontinuous symmetries like parity?

You find some discussion on symmetries in quantum field theory in my notes,

The (in my opinion) best qft books are

S. Weinberg, Quantum Theory of Fields, Cambride University Press (3 Vols.)

They cover symmetry principles very thoroughly.
