Classical Guitar Repertoire
This is a terrific site to find classical guitar pieces for free from old non-copyrighted publications. Just search for a composer or piece search box and look for results with pdf files attached.
Here's another site to find free music. It's a little easier to navigate, but not as comprehensive as the digital guitar archive.
