TITLE: Reference for Learning Global Class Field Theory Using the Original Analytic Proofs?
QUESTION [13 upvotes]: Hi Everyone!
I'm wondering if anyone knows of a reference for learning global class field theory using the original analytic proofs developed in the 1920s and 1930s. Almost every book I can find either does local class field theory first or uses ideles/cohomology to prove global class field theory. This is not how it was historically done - the ideal-theoretical formulation of class field theory was proven first, using more elementary analytic methods. So I'm wondering if anyone knows of any resources which would teach these proofs.
I'm currently about to take a class which follows global class field theory in this way, and our teacher says he does not know of any textbook for this, so I'm wondering if anyone here would know.

REPLY [5 votes]: "The" classical approach to class field theory can be found in Hasse's Marburg lectures from the early 1930s (in German, as of now). The key arguments are contained in Artin's three lectures on class field theory from 1932, given (in English) in the appendix of Harvey Cohn's book "A classical invitation of algebraic numbers and class fields".
Another nice introduction along the classical lines is provided by Iyanaga's "Class-field theory notes". Perhaps this is the book you're looking for. It's definitely more classical than Janusz. Recently, Nancy Childress has published a book on class field theory, which is
at least "semi-classical".
