Google's book search just came in very handy... I came across a phrase in ATTPL using the term 'dominated', and I wasn't completely sure of its definition. And of course, I couldn't remember where in 100 pages it was defined.
Fine, I'll search the Postscript version of the chapter that I have on hand. Wait, no. That doesn't work. PS != PDF. Sigh.
So I typed in a unique phrase from the book: that found the book on Google Books. Then I simply searched for the term. Wow, it immediately told me exactly what I wanted to know.
