After grinding through a bunch of compiler books I have to mention "Modern Compiler Implementation in C - Andrew A. Appel": http://www.amazon.co.uk/dp/0521607655 as one that stands out.

For LALR Parsers and DFA scanners and the like, I found the original Dragon Book http://www.amazon.co.uk/dp/B00EKYURHS is still best.

Both books are very accessible reading.
