Well, one book i'm currently reading is The Complete Yes Minister: http://www.amazon.com/The-Complete-Minister-Jonathan-Lynn/dp/0563206659. This is the the book version of the BBC comedy series. It really gives a nice insight why neither government nor management ever achieves something.
Of course, my most read document of the past years has been RFC2616: Hypertext Transfer Protocol -- HTTP/1.1.
