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?

The thirty-year old useless purple textbook with a beautiful picture of a wizard on the cover is a /g/ meme along with IBM model M keyboards, thinkpads and what not.

sicp is useless. you dont need books to program.
