Statistical NLP Book
First an explication: a few weeks ago I had a revelation that computational linguistics is the field for me. So, I found the best book I could on the subject, which seems to be Manning and Schuetze's Foundations of Statistical Natural Language Processing (FSNLP). Just reading the introduction on Google Books was enough to convince me to drop some hard cash. The writing is brilliant. I'm only through Chapter One, but it's already worth it.
