Textbooks in Text file???

I didn't know where to post this but I was wondering if anyone knew where I could get a textbook in some sort of text file??? I have the book but I want to be able to search key words and stuff.

Uh.. check the textbook's publisher's website?

I really doubt they'll have $100 textbooks available online for free in a textfile format.

Yeah that's what I was thinking but I figured I'd ask anyways.
