I am looking for a source (preferably online) for Weil's original 1952 paper on the explicit formula. I am aware of an english translation available here, but would like to have access to the original also.

Related question: I understand that Lang's Algebraic Number Theory gives a fair exposition of this paper. How accurate is this? Namely, is it good enough to follow Lang's presentation?

Commentaireat the end of volume 2. While "most" libraries might not have Weil's collected papers, it's the most natural place to look for this particular one. $\endgroup$ – Jim Humphreys Apr 10 '14 at 23:38
