Not included in the list so far is this book:
Basics of Compiler Design (Torben Mogensen)
(from the dept. of Computer Science, University of Copenhagen)
I'm also interested in learning about compilers and plan to enter that industry in the next couple of years. This book is the ideal theory book to begin learning compilers as far as I can see. It's FREE to copy and reproduce, cleanly and carefully written and gives it to you in plain English without any code but still presents the mechanics by way of instructions and diagrams etc. Worth a look imo.
