TITLE: Book(s) Request to Prepare for Algebraic Number Theory
QUESTION [14 upvotes]: I would appreciate suggestions for books to enhance my learning in algebra so as to be able to read Samuel's "Algebraic Theory of Numbers" and eventually at least begin Neukirch's "Algebraic Number Theory."
By way of background, I have gone through B. Gross's Harvard lectures on algebra several times. They were correlated to Artin, and included factoring and quadratic number fields, but did not cover modules or fields. Nor Galois Theory.
So I would like to get a good exposure to those areas that are particularly germane to ANT. (E.g. Artin does not have anything on perfect fields and only mentions algebraic closure in a short paragraph before the Fundamental Theory of Algebra.  
Thanks very much.

REPLY [3 votes]: Pierre Colmez has written an amazing text, entitled Éléments d'analyse et d'algèbre (et de théorie des nombres). Here's the table of contents. It's so technically precise and well digested that I think probably this book could serve as a nice reference for most of undergraduate analysis and algebra as well.  This text together with Samuel's book should be good preparation. There's also Dino Lorenzini's An invitation to arithmetic geometry, which I personally like quite a lot.
