Programming/development Books

So here's the deal. I dropped out of university... a few times... and have fallen back upon writing software for a living. I'm very conscious of the fact that having never studied it at college I am probably not following best practices etc.

I work mainly in C# but would like to expand my knowledge and study properly on my own. Anyone suggest any good texts for me?

tl/dr: Good programming books for students?

Racket;
It has a nice editor, but those guys don't seem to mingle much with the rest of the Scheme crowd.

Squeak;
Back to c2 wiki, or at least, impress me that this thing is useful for something.

Java;
UUGHH IHBT

The rest is okay.
