For beginning Classical Guitar Students:
Now I have to tell you, I don't teach Classical Guitar.  I like classical guitar and can play at a fairly basic level.  The method books I list here are great if you are working on classical without the aid of an instructor but if you really want to pursue classical guitar, I'd recommend you find an instructor who ONLY teaches classical guitar if possible.  Unfortunately, they can be a bit pricey but in my opinion,  that's the way to go if you decide to seriously pursue it.
