So the title pretty much says it all. I have completed a first course in Algebraic Number Theory (number fields, ideal factorization in the ring of integers, finiteness of the ideal class group, Dirichlet's units theorem) and I now want to move on to a second course. The two books that have been suggested to me are Lang and Neukirch (both called Algebraic Number Theory). I would like to hear people's opinions and comments about how these two compare for a graduate-level reading course in ANT.
Many thanks!
Neukirch is very complete and useful for future references, for example when you got into investigation. But it's a fat book.
Idk about Lang's book
