educate yourself on a budget

I was looking around to find an answer to a members question when I ran into this.
Never saw it before and am guessing others do not know about this either.
Type in a question and Google finds a book for you to search in , plus puts you on the right page.
Now this is cool.

That is way cool! I never heard of that before!
