TITLE: Text for Algebraic Number Theory
QUESTION [16 upvotes]: I have the privilege of teaching an algebraic number theory course next fall, a rare treat for an algebraic topologist, and have been pondering the choice of text.  The students will know some commutative algebra, some homological algebra, and some K-theory.  The texts I am now considering are 
(1) Frohlich and Taylor, Algebraic Number Theory, 
(2) Janusz, Algebraic Number Fields, and 
(3) Milne, Algebraic Number Theory (online).
I am leaning toward (1):  it seems very well written and has sections on cubic, biquadratic and sextic fields as well as quadratic and cyclotomic fields.  I do know that when you get into a course you discover drawbacks that aren't apparent when you're reading the text before the course begins.  Frohlich and Taylor is designed for a year long course and I only have one semester, so will need to do some selecting.  I regret not using any homological techniques, also.
I would appreciate suggestions, either about these or other texts.

REPLY [7 votes]: My favorite textbook on the subject is "Number fields" by Marcus. Things are done in a very explicit way, there are hundreds of exercises, and I've usually found that the proofs of the classical theorems (finiteness of the class number, structure of the units, ...) are done in a way that I really like.
