Have you yet discovered the glories of arxiv.org ?

Did you try the Google filetype:pdf search? Only PDF's will be returned.

As FZ said, the best source is Los Alamos National Laboratory (http://xxx.lanl.gov) or one of its mirror sites. However, the front page of that site is a bit sterile, and you have to know what you are looking for. That leads me to MIT's Net Advance of Physics (http://web.mit.edu/redingtn/www/netadv/welcome.html), which takes many documents (mostly from LANL) and alphebetizes them by subject, making it much more user-friendly.

And of course, right here at PF we have Physics Napster (http://www.physicsforums.com/showthread.php?threadid=31), where we have collected many, many links to free pdf books and articles.
