A good reference to begin analytic number theory I know a little bit about basic number theory, much about algebra/analysis, I've read most of Niven & Zuckerman's "Introduction to the theory of numbers" (first 5 chapters), but nothing about analytic number theory. I'd like to know if there would be a book that I could find (or notes from a teacher online) that would introduce me to analytic number theory's classical results. Any suggestions?
Thanks for the tips,

I'll try introduce something different from the other answers: Kiran Kedlaya's course notes for Analytic Number Theory seem like a good option.
An updated version is here.
